Temple Mountain

Led by: Benjamin Burger

Join us on an exciting field trip to Temple Mountain, where we'll embark on a geological adventure spanning a remarkable period in Earth’s history. Our journey will take us through the end-Permian mass extinction period, as we explore the rocks and collect fossils that hold clues to Earth's ancient history.

Along the way, we'll also visit historical uranium camps, including the very mine that supplied Marie Curie with the ore she used in her groundbreaking experiments on radioactive elements, and won her two Nobel Prizes.

Our first stop will be at the early Triassic Sinbad Limestone, where we'll have the chance to collect invertebrate fossils, giving us a glimpse into marine life recovering from Earth’s Worst Mass Extinction. Next, we'll visit the late Permian Kaibab Limestone, offering us insights into what life was like before the extinction, in the late Permian.

This full-day trip is excellent for anyone who loves rugged, backcountry driving and enjoys fascinating, roving lectures. Participants must be able to undertake a few steep hikes to important rock outcrops along the route.

Prepare for a full-day journey filled with geological wonders and historical significance that will leave you with a deeper understanding of our planet's rich past.

  • The route requires high-clearance vehicles, but we've arranged for parking at the campground for those with 2WD vehicles to join the field trip by catching a ride, as the field will loop back.

    In case of inclement weather rendering roads impassable, we have an exciting alternative plan to explore the remarkable features of Goblin Valley State Park a few miles to the south and delve into the mysteries of Jurassic sedimentary rock formations.

  • Bring lunch, water, sturdy shoes, binoculars, camera, and snacks.
