Geology at Bear Lake

This spot sits on Sedimentary rocks (Ordovician and Cambrian), mapped as limestone and dolostone that formed roughly 540 to 445 million years ago. Limestone like this typically forms in ancient seas, so marine fossils such as brachiopods, corals, and crinoids tend to weather out of fresh exposures.
