Abundant trilobite fossils, including Elrathia kingi shown here, can be found within the Wheeler Shale east of Notch Peak in the House Range.
Many of the dry desert peaks of western Utah tell a story of shallow tropical seas. As much as 500 million years of deep burial, uplift, and erosion have changed layers of organic mud to cliffs and ledges of layered limestone. Closer inspection reveals abundant fossils, evidence of ancient sea life.
