Book Review – Two young-Earth creationist books about Yellowstone expose how YECs cannot explain Yellowstone geology

Your Guide to Yellowstone and Grand Teton National Parks: A Different Perspective, by John Hergenrather, Tom Vail, Mike Oard, and Dennis Bokovoy

The Geology of Yellowstone: A Biblical Guide, by Patrick Nurre

Young-Earth creationists (YECs) believe that the Bible requires that almost all features of Earth’s crust are the result of Noah’s Flood about 4300 years ago. These books are, in the words of Nurre, “an attempt to present the geology of Yellowstone from a Biblical perspective,”, as opposed to the standard geological timeframe in which the history of Yellowstone goes back a few billion years to the Archean Eon. This “biblical geology” effort is misguided, however, as the Bible does not say anything about processes such as igneous intrusion, volcanism, erosion, sedimentation, metamorphism, and glaciation. This results in a serious over-reading of the biblical text, leading to erroneous conclusions about the origin of geological features in places such as Yellowstone.

As a Christian, I believe that “In the beginning God created the heavens and the Earth” (Genesis 1:1), and I believe Noah’s flood was a real, historical event, though I believe it was local, not global, in extent and effect. The biblical account of Noah’s flood (Genesis 6-9) tells us nothing about how the igneous, sedimentary, and metamorphic rocks of Earth’s crust came to be, especially in places as far from biblical lands as Yellowstone. There is, therefore, no need to come up with a “biblical” explanation for Yellowstone.

Your Guide to Yellowstone and Grand Teton by Hergenrather et al.

yourguidetoyellowstoneThis is a well-written, nicely-illustrated book. Of the four authors, Dennis Bokovoy has a MS degree in geology, which helps to ensure that the book at least uses geological terms correctly. Michael Oard is a prolific writer on a wide range of topics in the YEC movement. The other two authors are John Hergenrather and Tom Vail.

Much of the book consists of typical tourist guidebook information: what to see at Old Faithful, Mammoth, Canyon Village, and so forth. The overall premise of the book, however, is that the geologic features of Yellowstone can be better explained in a so-called biblical model, which actually goes far beyond anything the Bible says.

As in most YEC literature, the book presents the alternatives as either evolution over millions of years, or creation less than 10,000 years ago. Many who read this book, either Christian or non-Christian, will not be aware that these are not the only options. There are many highly-qualified theologians, pastors, and scientists who accept the Bible as inerrant and authoritative who reject the overly-literal young-Earth interpretation of Genesis.

The book is fairly shallow in terms of its presentation of the case for a young-Earth interpretation of Yellowstone. It is admittedly written for a general audience, but it fails to develop a convincing case that the geologic features of Yellowstone are better explained by Noah’s flood, acting just a few thousand years ago.

The Geology of Yellowstone by Nurre

geology of yellowstoneThe biography at the back of the book states that Patrick Nurre “has been a rock hound since childhood.” I found one site that said he was “trained in secular geology,” but it seems he does not have a degree in geology.

Early in the book, Nurre states: “Secular geology claims that the universe is 15 billion years old and the Earth is about 4.6 billion years old. If this is true, then the entire Bible is a lie!” [emphasis added]. This false dichotomy of “either young-Earth creationism is true or the Bible is false” has driven countless young people out of the church, and has set up an unfortunate barrier to faith for many scientifically-literate people. When people see the only options as young-Earth creationism or rejection of Christianity, many opt for a rejection of Christianity, especially in light of the steady stream of bad science that has come out of the young-Earth movement over the past century. I believe the Bible is inerrant and trustworthy, and that all truth is God’s truth, whether revealed in Scripture or in creation. An alternative way to look at Earth history, then, is that if there seems to be a conflict between science and the Bible, then either our interpretation of science is wrong, or our interpretation of the Bible is wrong. In this case, if Earth is old, it is not that “the entire Bible is a lie,” but that it could be that the young-Earth interpretation is what is at fault. Being that there are alternative interpretations of the opening chapters of Genesis held by Bible-believing Old Testament scholars, and that young-Earth geology does not work, I side with old-Earth biblical interpretations.

The errors in the book are numerous:

  • p. 19. Radioactive half-life is described as “the time it takes for ½ of a Carbon-14 atom to decay.” – There is no such thing as the decay of half of an atom.
  • p. 22. “The column in its entirety has not been found anywhere on the Earth.” – Complete geologic columns, containing rocks from all periods from the Cambrian through Quaternary, are found in a number of places on Earth, such as in the Williston Basin of northwestern North Dakota.
  • p. 23. In regards to uranium-lead dating methods: “We assume that the initial state of the rock started with a certain amount of uranium and no lead.” – I’m not sure that the author understands uranium-lead dating, as methods such as isochron dating and concordia methods, are based on the assumption that there was initial lead in the system.
  • p. 89. “Igneous Rocks – rocks geologists think were formed by fire or heat.” – This is a really bad definition of igneous rocks. They certainly were not formed by fire, which is the result of combustion reactions. Heat is also involved in the formation of metamorphic rocks, and even in the sub-metamorphic alteration of many sedimentary rocks at a few hundred degrees Celsius.
  • 94. “Obsidian is volcanic glass: pure quartz.” – Pure quartz has a composition of crystalline SiO2 and nothing else. Obsidian is not crystalline, so it is not quartz, and obsidian contains many other elements, such as iron, magnesium, aluminum, sodium, and potassium, which pure quartz does not contain. This mistake is repeated a number of times in the book.

I could list many more, but you get the idea. Even if I were still a YEC, I would not endorse this book.

Analysis

Both books give typical young-Earth creationist explanations for the rocks and other geologic features of Yellowstone. I will take a closer look at two of these, showing why it is not credible to squeeze the history of Yellowstone into the short time frame required by YECs.

Fossil Forests

The fossil forests of Yellowstone are found in the Eocene Absaroka Volcanic Supergroup, which covers an extensive area north, east, and southeast of Yellowstone National Park. These rocks were formed as the result of the eruptions of a series of large stratovolcanoes, similar to the volcanoes of the Cascade Range. Many of the rocks are interpreted to be volcanic mudflow deposits (lahars) rather than as lava flows.

The authors of both books point to the 1980 eruption of Mt St Helens in Washington for an explanation for the petrified forests of the Absaroka Supergroup. Spirit Lake at Mt St Helens contains many thousands of trees that could eventually be incorporated into sedimentary rocks as a fossil forest. The young-Earth thinking is that if a single local catastrophe like Mt St Helens could create a local fossilized forest, then a much larger catastrophe (Noah’s flood) could create much larger fossilized forests such as found at Yellowstone.

It is valid to consider the deposits from contemporary volcanic eruptions, such as the 1980 eruption of Mt St Helens, when seeking to interpret the formation of ancient rocks such as in the Absaroka Volcanic Supergroup. What we learn from modern eruptions is that volcanoes can produce lahars, which may contain logs and tree fragments, which will lead to layers of rock with petrified wood. It is legitimate, therefore, to conclude that the petrified forests of Yellowstone very well may have been formed in an analogous way.

The problems with the YEC interpretation of fossil forests at Yellowstone are numerous, and are not addressed in these two books:

  • How did a series of large stratovolcanoes form and then completely erode away in a matter of weeks, which is what would have been required in the most-common young-Earth catastrophism scenario?
  • All that remains of the stratovolcanoes themselves are igneous intrusions that represent the magma chambers. How did these magma chambers crystallize in a matter of days or weeks before they were exposed by floodwater erosion?
  • All of the sediments in these lahars (volcanic mudflow deposits) seem to be locally-derived, from the adjacent stratovolcanoes. If this happened during a global flood, why are there not non-local sediments mixed in with the local sediments?
  • Likewise, all of the trees seem to be part of an ecological package, ranging from subtropical species in the lowlands to colder-climate conifers higher up on the volcanic slopes. This makes perfect sense in the standard geological explanation, as lahars would originate at higher elevations and wash down to lower areas, creating a mixture of trees from different ecological zones. In the young-Earth scenario, however, there would be no time for trees to grow on the slopes of the ephemeral volcanoes, so there is no explanation of how these trees, and not some other mix of trees, ended up being preserved in the Absaroka volcanic rocks of Yellowstone.

Yellowstone Caldera and Quaternary Glaciation

The Yellowstone Caldera is the result of the most recent “supervolcano” eruption at Yellowstone. The Yellowstone area has actually been the home to two supervolcano eruptions (volume > 1000 km3), several smaller caldera eruptions, and numerous smaller, though often still enormous, rhyolitic and basaltic lava flows. The present Yellowstone caldera is largely filled by these later flows. All of these eruptions occurred in what geologists refer to as the Quaternary period, which covers the past 2.6 million years of Earth history. YECs believe that this volcanism occurred at the end of Noah’s flood, or during a few centuries after the flood.

Both books refer often to the volcanism associated with the Yellowstone Caldera, without explaining how this is better explained by YEC, or acknowledging the numerous problems with trying to squeeze more than sixty distinct volcanic eruptions into a short period of time. There is abundant evidence for unconformities (erosional surfaces) between lava flows. This requires that lavas had time to completely cool between eruptions, something which takes time.

A fatal complication for the YEC explanations regarding Quaternary volcanism at Yellowstone is the evidence for alternation between volcanism and glaciation on the Yellowstone Plateau. Young-Earth creationists insist that there was only one ice age following Noah’s flood (though of course the Bible says nothing about when or how many ice ages occurred), yet at Yellowstone it is clear that a massive ice cap formed over the higher elevations more than once. For instance, volcanic ash from the final large caldera eruption (Lava Creek Tuff) is found on the Great Plains in Saskatchewan sandwiched between glacial deposits, which means there was glaciation both before and after this caldera eruption. Furthermore, a lobe of one of the final large rhyolite flows overlies glacial moraines near West Yellowstone, indicating that an ice cap had had time to form between emplacement of these later lava flows.

Here is what the Quaternary history of Yellowstone would have to look like in the young-Earth model:

  • Numerous smaller basalt or rhyolite lava flows, with time for erosion and deposition of sediments between at least some of the flows.
  • Supervolcano eruption – Huckleberry Ridge Tuff (2500 km3).
  • More smaller basalt and rhyolite flows, with time for erosion and sedimentation between flows.
  • Caldera eruption – Mesa Falls Tuff (280 km3, not large enough to be a supervolcano).
  • More smaller basalt and rhyolite flows, with erosion and sedimentation.
  • Formation of an ice cap over the Yellowstone Plateau.
  • Supervolcano eruption – Lava Creek Tuff (1000 km3).
  • More smaller basalt and rhyolite flows, with time for erosion and sedimentation between flows.
  • Formation of another ice cap over the Yellowstone Plateau.
  • At least one more massive rhyolite flow.
  • Formation of a final ice cap over the Yellowstone Plateau, and melting of that ice cap.

The whole thing can be summarized as “too many events, too little time.”

I would not recommend either of these books for use by Christians seeking to gain understanding of the geologic history of Yellowstone National Park. The Bible does not say anything about geologic events such as volcanism and glaciation, so YEC efforts to explain the geology of places such as Yellowstone is biblically unwarranted. Furthermore, YECs have been unsuccessful in explaining the complexity of geological features at places such as Yellowstone.

One can be a Bible-believing Christian and not hold to belief in a young Earth or global flood. A few of these alternative interpretations are presented in the Report of the Creation Study Committee of the inerrancy-affirming Presbyterian Church in America.

Yellowstone National Park — Another bad answer from Answers in Genesis

1280px-Grand_Prismatic_Spring_and_Midway_Geyser_Basin_from_above

This brief article on Yellowstone National Park from Answers in Genesis is exceptionally bad.

https://answersingenesis.org/creation-vacations/yellowstone-national-park/

Answers in Genesis — “The volcano that left the enormous crater at Yellowstone was far greater than anything we observe today. While modern craters measure barely 20 square miles (52 km2), the crater at Yellowstone covers about 1,500 square miles (3885 km2). You can still see the massive volcanic lava and ash beds at Specimen Ridge and other places north of the park.”

Response — The 3885 km2 caldera must refer to the 640,000 year-old Yellowstone Caldera, which produced the Lava Creek Tuff. This was the third of the three major Quaternary calderas formed at Yellowstone. The volcanic and volcaniclastic deposits at Specimen Ridge, however, are related to entirely different set of volcanoes, and have nothing to do with the Yellowstone Caldera eruptions. The rocks at Specimen ridge are part of the Eocene Absaroka Volcanic Supergroup, which was created by a series of stratovolcanoes similar to those in the Cascade Range.

Answers in Genesis — “The fact that molten rock remains hot near the earth’s surface is evidence that Yellowstone’s volcanic activity was recent—fewer than 4,500 years ago, according to the Bible´s timescale. So every one of the park’s 100,000 geysers, hot springs, and mud pots is a testimony to the recent Flood.”

Response — In other articles, Answers in Genesis admits that Yellowstone sits over a hot spot, so there is a very credible explanation for why rocks beneath Yellowstone are still hot even after hundreds of thousands of years. Heat is continually supplied from Earth’s mantle, which explains why magma exists at relatively shallow depths. The presence of heat in no way points to the young-Earth creationist timescale, and there is nothing in these volcanic rocks that points to the young-Earth creationist’s global flood.

Answers in Genesis — “If you look along the western shore of Jackson Lake, you can see the Teton Fault, which marks the boundary between where the mountains rose and the nearby land fell. The evidence indicates that most of the world’s mountain ranges rose very recently because their dazzling heights and ruggedness have not had time to erode away.”

Response — Here, Answers in Genesis seems to be assuming that Earth is a rather static world, rather than dynamic planet. If the Grand Tetons had been sitting there static for tens of millions of years, then the mountain range would now be leveled down to low hills at best. But if the Grand Tetons and other mountain ranges are actively rising (and there is abundant evidence that this is still the case) then there is no reason why they would not be majestic and rugged mountain ranges at present.

Answers in Genesis — “The fact that magma is still hot enough to drive the geysers indicates that the magma moved to this chamber very recently (at the end of the Flood, not millions of years ago).”

Response — Once again, Answers in Genesis is ignoring how Earth works. Heat from Earth’s mantle is continually supplied beneath Yellowstone, keeping the rocks hot enough to be partially molten. There is no reason to suppose that the magma moved into this chamber only 4500 years ago.

Answers in Genesis — “Notice that the stumps are stripped bare, without any signs of roots or soil.”

Response — The fact that petrified tree stumps are “stripped bare” is evidence that they were moved in debris flows (lahars), rather than being petrified in the place where they grew. There is abundant sedimentological evidence that these petrified trees are in localized debris flows. There are also tree stumps that do have roots, and some may be in their original positions.

Answers in Genesis — “If the Flood stripped the earth’s forests and then the trees floated on the ocean and jostled about, rubbing together before sinking, it could more easily cause many layers of stumps.”

Response — The evidence in the rocks is that these fossil forests were buried in local debris flows: gravelly muds with the consistency of liquid concrete that solidified to form conglomerates. The rocks containing these trees are all local volcanic rocks, derived from volcanoes which were a few tens of kilometers away at the most. If the trees were floating on an ocean, how did they get mixed in with the debris flows? Additionally, if the trees were floating on an ocean, why did they all deposit in one layer on top of another in the same place, rather than some being deposited in northwestern Wyoming, and some in central Nebraska, some in northern Idaho, and so forth? A global flood would have scattered the trees, not deposited them in layers one on top of another.

Answers in Genesis — “Scientists observed something similar to this happening at Spirit Lake after Mount St. Helens erupted in 1980.”

Response — Young-Earth creationists love to point to Mt. St. Helens. Yes, the log deposits of Spirit lake at Mt. St. Helens can tell us some things about how petrified forests might be preserved in volcanic deposits, but that is about all they can tell us. The trees at Spirit Lake, however, will end up being preserved in a lake deposit, not in a debris flow deposit, and almost all of the Yellowstone petrified forests are found in coarse conglomerates, not in fine-grained lake deposits.

Answers in Genesis — [in a section on Grand Prismatic Spring] “What makes the dazzling colors at the park’s largest hot spring?”

Response — The picture in this section of the article is not Grand Prismatic Spring.

Answers in Genesis — [in a section on Old Faithful Geyser] “The fact that magma is still hot enough to drive the geysers indicates that the magma moved to this chamber very recently (at the end of the Flood, not millions of years ago)”

Response — The picture in this section of the article is not Old Faithful Geyser. I don’t think the author of this article is all that familiar with Yellowstone National Park. In addition, geologists do not say that the magma beneath Yellowstone National Park was intruded into Earth’s crust millions of years ago, as the most recent caldera eruption has been dated at 640,000 years, and the most recent large lava flow at Yellowstone (the Pitchstone Plateau flow) occurred about 75,000 years ago.

Answers in Genesis — “Look at those pretty colors in the pool, Daddy. But what´s that smoke? Is it hot?”
“Yes, honey. It´s very hot. In fact, springs like this are hot because super-hot, molten rocks, called magma, rose from deep in the earth during Noah´s Flood—just a few thousand years ago. The heat hasn´t had time to cool off.”

Response — Answers in Genesis managed to squeeze a lot of bad science in such a short article. For Daddy to give his child the Answers in Genesis explanation for the features in Yellowstone National Park could eventually lead to shipwrecking that child’s faith. If this child grows up and studies geology, he or she will discover that almost everything Answers in Genesis taught them about the Earth is wrong. If this bad science is coupled with the false dichotomy of “If young-Earth creationism isn’t true, then the Bible isn’t true and Jesus didn’t die for your sins,” they could easily throw out their Christianity along with their young-Earth guidebook to Yellowstone National Park.

My hope instead is that this child will grow up with foundations for their faith that are built on God’s Word, but not on the bad science of young-Earth creationism.

I have barely touched the surface on what I could write about why Yellowstone National Park and young-Earth creationism do not go together. Of course, the Bible is not about Yellowstone National Park.

Young-Earth creationism and the intensity of volcanism

The June 2012 issue of the Institute for Creation Research’s Acts & Facts magazine came to my mailbox this week, and the short article “Volcanoes of the Past” by John D. Morris caught my attention. The article argues that Noah’s flood was a time of massive volcanic eruptions (“supervolcanoes”), and that volcanic activity on Earth is now experiencing a rapid post-Flood decline.

The cornerstone of young-Earth creationist (YEC) geology is the belief that Noah’s Flood was global in extent, occurred sometime around 2300 BC, and is responsible for most of Earth’s geological features. For a variety of reasons that I have discussed elsewhere (here, here, and here for example), I don’t think that any of this is Biblically necessary nor scientifically viable. A corollary of this “Biblical Catastrophism” or “Flood Geology” is that the catastrophic activity of Noah’s flood continued after the deluge, but with exponentially declining intensity over time. According to this theory—which is not held by all YECs—the centuries after the Flood were chaotic times, with rapidly changing climate (including a single ice age), rapid sedimentation, and biological diversification. According to some, much of Earth’s Cenozoic record was deposited during these few short centuries. The difficulties with this scenario are almost as numerous as the problems with YEC flood geology, but I won’t get into that now.

The heart of Morris’s argument is that we see evidence of massive “supervolcanoes” in the rock record, and that we don’t have any of these erupting today, which is a true statement. Furthermore, if one plots the volume of material extruded by historic volcanoes, one sees a decline over time. This statement is quite simply not true. In his own words,

Through an understanding of today’s volcanic eruptions, we can better comprehend those of the past. However, the rock record of the past suggests that yesterday’s volcanoes were evidently “supervolcanoes,” accomplishing geologic work hardly comparable to those we currently observe.

If we plot the volume of ash and lava extruded by volcanoes throughout history—comparing Vesuvius (79 A.D.) and Krakatoa (1883) to more recent volcanoes, such as Mount St. Helens (1980) and Pinatubo (1991)—we come to the conclusion that the earth processes are quieting down. Then if we plot the materials blown out by volcanoes that erupted during the great Flood and soon thereafter (inferred only from the materials left behind), then we conclude an exponential decline in the power of earth’s volcanoes over time. Flood volcanoes were many times greater than those recently witnessed.

The article includes a graphic showing volumes of volcanic products from several eruptions, with an obvious decline from the Huckleberry Ridge Tuff from the Yellowstone (Island Park) eruption (2500 km3), down through Mount St. Helens (a mere 1 km3).

A person with little or no geological background reading the article and examining the figure could only come to one conclusion: There has been a steady decline in the intensity of volcanism on Earth. There are a number of problems, however, with Morris’s article.

First, Morris’s graphic is rather deceptive, especially given the content of the accompanying text. These five eruptions are portrayed from oldest to youngest, and from largest to smallest. What the diagram doesn’t show, however, is that there are many thousands of volcanic eruptions throughout the same time period which don’t fit the YEC post-Flood residual catastrophism model. The following graphic from the US Geological Survey gives a much more realistic depiction of the variability of volcanic intensity over time:

This USGS diagram is highly selective as well, as it lists only a handful of eruptions, but it is much more representative of actual trends. The Holocene (Recent) Epoch—which all YECs would consider post-Flood—has a history of a wide range of volcanic eruptions, ranging from very small to large eruptions such as that of Tambora in 1815 and Mount Mazama approximately 7700 years ago. There is no evidence that I know of that the frequency or intensity of any eruption type is decreasing with time. Instead, smaller eruptions are occurring almost continuously around the world, while the larger eruptions occur with frequencies measured in centuries or millenia.

Morris named four historic eruptions as part of his evidence that volcanism on Earth is slowing down.

If we plot the volume of ash and lava extruded by volcanoes throughout history—comparing Vesuvius (79 A.D.) and Krakatoa (1883) to more recent volcanoes, such as Mount St. Helens (1980) and Pinatubo (1991)—we come to the conclusion that the earth processes are quieting down.

These four eruptions—out of thousands he could have chosen—don’t even illustrate the trend that Morris is advocating. Rather than going from larger to smaller, the trend makes a zig-zag:

One could selectively choose four or more eruptions to show any trend they wanted: increasing volume, decreasing volume, steady volume, or random. It would be far better to look at thousands of eruptions over a long period of time, and Morris has not done that.

The second problem I want to mention is that the eruptive history of the Yellowstone region is far more complex than Morris implies. The figure in the article shows the products of two Yellowstone-related eruptions: the Huckleberry Ridge Tuff and Lava Creek Tuff. There have actually been three large eruptions from the Yellowstone area:

  • Island Park Caldera, Huckleberry Ridge Tuff, 2.1 million years, 2500 km3
  • Henry’s Fork Caldera, Mesa Falls Tuff, 1.2 million years, 280 km3
  • Yellowstone Caldera, Lava Creek Tuff, 0.6 million years, 1000 km3

The trend is from largest to smallest to something in-between. Again, Morris selected the two eruptions that supported his thesis and ignored the other eruption.

But there is much more to the story of Yellowstone. In between the mega-eruptions, and in the time since the most recent, Yellowstone has had numerous smaller eruptions of rhyolitic and basaltic lava. Therefore the trend in Yellowstone is really mega-small-mega-small-mega-small. But there is more: the Yellowstone volcanic area is part of a string of volcanic centers that extend from northwestern Nevada through the Snake River Plain up to the area of most recent explosive activity in Yellowstone. There have been dozens of “supervolcano” eruptions along this trend, with hundreds or thousands of smaller eruptions in between.

A third problem with Morris’s article is that the more ancient rock record isn’t just a history of supervolcanoes. Throughout Earth history there have been large volcanoes and small volcanoes. The large volcanoes include explosive “supervolcanoes” such as Yellowstone Caldera, Long Valley Caldera, and Toba, Indonesia; and also flood basalts (the term “flood” has nothing to do with Noah’s flood) such as the Columbia River Basalts. But throughout the same time period there have been numerous smaller eruptions, whether from stratovolcanoes such as Mt. Fuji or Mt. Rainier, or from even smaller volcanoes such as cinder cones and maars.

It is clear that there is no trend in Earth history going from larger volcanic eruptions to smaller. Young-Earth creationists might counter by saying that it is still a fact that there have been massive volcanic eruptions in the past, and that none of these are occurring today. The standard geological explanation is that the larger the eruption, the greater the time gap between eruptions. Yellowstone apparently erupts every 0.6 to 0.9 million years; we may be due for an eruption, but it could still be hundreds of thousands of years away. These eruptions are spaced too far apart to say whether or not their frequency is changing over time.

The YEC has a greater problem, and that is trying to fit a large number of very large eruptions into a very short time. If the Yellowstone eruptions occurred after the Flood (the distal ash is in what most YECs would call post-Flood deposits), then three very large eruptions had to occur in the span of a few centuries perhaps just a little more than 4000 years ago. In between these eruptions there would have had to have been time for weathering, vegetation growth, and a number of smaller volcanic eruptions. All of these volcanic deposits would have had to be emplaced in time for the Ice Age, which lasted only a few hundred years. And all of this is a gross oversimplification of everything that would have had to have happened in a very short period of time.

Unfortunately, most Acts & Facts readers will be completely unaware of the numerous weaknesses in this article. Morris has not made a case that the frequency or intensity of volcanism is decreasing with time.

With love for my YEC brothers and sisters in Christ, and with prayerful concern for those who are turned away from Christianity by bad arguments in defense of the Bible.

———————————————————————–

P.S. This post-Flood residual catastrophism concept actually has led to one of the best papers to come out of the YEC movement, Earthquakes and the End Times, by Austin and Strauss. A common claim among end-times prophecy teachers is that the frequency and intensity of earthquakes has been increasing over time, leading up to the return of Christ. Austin and Strauss refute this teaching, calling it a Christian urban legend. One impetus behind the article, aside from the fact that there is no geological evidence for an overall increase of earthquake activity on Earth, is this YEC idea that intensity of all sorts of geological activities should be declining over time. I briefly discussed the “Earthquakes and the End Times” article back in 2007 (here).

Mountain lion in St. Louis County! — This doesn’t happen too often. A night-time wildlife camera captured a mountain lion in suburban St. Louis, less than ten miles from our home. We’re a little more used to opossums, raccoons, deer, and wild turkeys around here.

I don’t worry too much about mountain lions when hiking in Missouri. I’ve never seen one in the wild while hiking in the West (I’ve lived in Montana, Utah, and Colorado), but I suspect they have seen me.

Yellowstone Supervolcano eruption NOT imminent — From National Geographic: Yellowstone Has Bulged as Magma Pocket Swells. The ground within the Yellowstone Caldera has swelled upwards up to ten inches (25 centimeters) as magma slowly intrudes into a magma chamber 10 kilometers beneath the surface.

“At the beginning we were concerned it could be leading up to an eruption,” said [University of Utah geologist] Smith, who co-authored a paper on the surge published in the December 3, 2010, edition of Geophysical Research Letters.

“But once we saw [the magma] was at a depth of ten kilometers, we weren’t so concerned. If it had been at depths of two or three kilometers [one or two miles], we’d have been a lot more concerned.”

Apparently, intrusion into the magma chamber is somewhat cyclical:

Based on geologic evidence, Yellowstone has probably seen a continuous cycle of inflation and deflation over the past 15,000 years, and the cycle will likely continue, Smith said.

Surveys show, for example, that the caldera rose some 7 inches (18 centimeters) between 1976 and 1984 before dropping back about 5.5 inches (14 centimeters) over the next decade.

IBM Supercomputer wins Jeopardy — The 1997 computer victory over chess champion Garry Kasparov was nothing compared to this one. Chess is complex, but the logic of chess is nothing compared to the complexities of language as expressed in the TV gameshow Jeopardy. PCmag.com reports that the Watson supercomputer defeated two Jeopardy champions at the game, which means that the computer could understand the nuances of the categories and questions (actually the answers). The author believes that artificial intelligence (AI) will operate at human levels within two decades, and adds “I for one would then regard it as human.” He continues, “By the time the controversy dies down and it becomes unambiguous that nonbiological intelligence is equal to biological human intelligence, the AIs will already be thousands of times smarter than us.”

My questions:

  • Is there more to being human than being able to process information? (The Christian answer is “yes.” Humans are created in the image of God, and some things such as genuine emotions just cannot be programmed.)
  • How long will it be until someone falls in love with a computer? Until someone gets married to a computer?
  • What will stop the Episcopal Church or ELCA from ordaining computers as pastors? (Too bad these denominations don’t require baptism by immersion; that would prevent computers from being eligible for ordination).

My thumbs up to taking the kids to Niagara Falls, Devil’s Tower, Mount Rushmore, the National Air and Space Museum, and the Grand Canyon (I’ve never been there).

For what its worth, here is my list of ten great places I’ve taken my kids to, in no particular order:

  1. Yellowstone National Park — How in the world did this not make the Yahoo list?
  2. The Eiffel Tower, Paris — I’m sure it beats the Brooklyn Bridge hands down.
  3. Bucharest, Romania — Doesn’t make most people’s list of top spots, but my children have tons of wonderful memories of spending over five years of their childhoods in Romania.
  4. Arches and Canyonlands National Parks, Utah — A wonderful family vacation.
  5. Mountain biking near Red Lodge, Montana, and Reutte, Austria — I wish I could do this with the family a whole lot more often.
  6. Great nature museums — The Museum of the Rockies in Bozeman, Montana, and the Denver Museum of Nature and Science.
  7. Great art museums — The Louvre and Musee d’Orsay in Paris, the Alte Pinakothek in Munich, and the St. Louis Art Museum.
  8. St. Louis, Missouri — Free zoo, free art museum, Missouri Botanical Gardens, St. Louis Cardinals baseball games.
  9. Beartooth Highway, Montana and Wyoming — The most amazing and scenic highway in America.
  10. Whitewater rafting, Arkansas River, Colorado — I did this with two of my kids this summer, plus rappelling.

Places we haven’t been that I’d like to take my kids to:

  1. The Grand Canyon — my dream trip.
  2. Glacier National Park, Montana — I’ve been there, but the kids haven’t.
  3. Ekalaka and Miles City, Montana — I had to go there as a kid, why shouldn’t they? And the museum in Ekalaka has a two-headed calf!

Grace and Peace

P.S. The entire family says, “No, not Miles City and Ekalaka!”
