Billings Gazette geology videos

The Billings Gazette has three short videos on the geology of the Billings, Montana area featuring Rocky Mountain College geology professor Derek Sjostrom:

Geology of the Beartooths — Montana’s highest mountain range (Granite Peak, 12799 ft, 3902 m) has a core of 3.2 billion year old metamorphic rocks.

Geology of the Pryors — The Pryor Mountains (East Pryor Mountain, 8786 ft, 2678 m) south of Billings are formed mostly of blocks of Paleozoic sedimentary rocks.

Geology of the Rimrocks — The Rimrocks are Cretaceous sandstone cliffs on the north side of Billings. The fossils and structures indicate that the Eagle formation formed in a barrier island setting, much like modern Padre Island in Texas.

These are at a very basic level, but I still enjoyed them, and it looks like there are more to come in the series.
