On Saturday, my family and I had the pleasure of taking a geological tour of the area at the base of the Front Range, just west of Denver. Our tourguide (it was just me and my family) was a USGS geologist who is a member of the Affiliation of Christian Geologists. We started with the unconformity between Precambrian metamorphic rocks (~1.75 billion years old) and the Pennsylvanian/Permian Fountain Formation (~300 million years) exposed behind Red Rocks Amphitheater. We ended up on Dinosaur Ridge, which has exposures containing dinosaur bones (in the Jurassic Morrison Formation) and dinosaur footprints (in the Morrison and in the Cretaceous Dakota Formation). I had been at most of the sites we examined, but of course there is always more to see.
I learned a lot, and my family had a great time too.
Grace and Peace
