Spend eight hours digging through half a billion years of shale to uncover museum-quality trilobites west of Delta, Utah. This guided quarry access day combines hands-on paleontology instruction with practical fieldwork in an open desert setting.
More ways to explore the area's outdoor wonders
The wind opens the desert like a page and the shale seems to dare you to look closer. On a full-day quarry access trip an hour west of Delta, Utah, you step onto an exposed Cambrian shelf where layers of 500‑million‑year‑old mudstone break apart under your fingertips. Under an operator’s instruction you learn to spot the crescent shape of a trilobite before you pry it free — a slow, rewarding rhythm of sifting, tapping and piecing together a very ancient life.
