Here is a small trip only minutes away from downtown Salt Lake City. If you would like the exact location, PM me. I hadn’t been to this site in a couple years so it took @Earth Chemistry and I a couple hours to re-discover it so here’s a little history about the area. Ok first, the structural geology in this area is quite famous as it is a large pair of synclines. From https://geology.utah.gov/wp-content/uploads/synclines.gif They were made in the Sevier Orogeny about 120 Ma to 50 Ma ago.
Hey guys. I’ve got this bivalve that needs a labeling. I collected it from the Jurassic age Twin Creeks Formation on the east side of Salt Lake City. It has some shell material left but most of it is an internal mold.
So I’m still snowed in so here’s a trip from warm Early June. My friends and I wanted to hit all the closest rock locations around Salt Lake City and search for fossils and cool sedimentary geology (a couple of them being sedimentary geologists). We visited the Southern Oquirrh Mountains and a few canyons over on the east side of the valley at the base of the Wasatch Mountains. Here are the stratigraphy columns for both provided by Geolgic History of Utah by Lehi F. Hintze and Bart J. Kowallis. I did not lead this trip so I am not certain which rock layers the fossils were each from (I’ll point out the ones I do know) but I’ll say we went through the Cambrian and Mississippian in the Oquirrh Mountains and basically everywhere on the Salt Lake City column.
