If the idea of spending the day digging up trilobites and stories of the past excites you, Antelope Springs is the perfect destination for your rockhounding adventure. This area is a gold mine for minerals and fossils with an exciting history of discoveries. Some visitors also encounter etchings of names from past visitors dating back 100 years. What could you find on your Antelope Springs excursion?
ABOUT THE AREA
Antelope Springs is best known for being the site of Antelope Springs Cave and the historical Antelope Springs Civilian Conservation Corps (CCC) Camp, giving you additional places to explore while searching for minerals and trilobites! The cave is Utah’s tenth-longest, spanning 0.61 miles, and is not for the faint of heart. Its entrance is gated due to its steep 20-foot drop, and visitors must be permitted to get the key and venture through its tight spaces.
The CCC campsite was opened in 1935 and used as a recreation site for Topaz internees, youth groups, and adult hikers. Only a few slabs of concrete remain today, but if you’re willing to hike through a bit of sagebrush, there’s no telling what you might find while geocaching around the site. History buffs may also appreciate the old Antelope Springs homestead!
Today, the Bureau of Land Management (BLM) owns Antelope Springs. The large U-Dig commercial trilobite quarry, the recently opened A New Dig site (open on Sundays), and smaller fossil quarries are some of the most popular destinations in the area. It’s said that Millard County is one of the best locations in the world for rockhounding because of the variety of rocks and exhilarating rare finds. Much can be found in our West Desert country, from precious gems to ancient fossils. You never know what mysteries you’ll find underground!

The Antelope Springs area offers public and private quarries, so make sure you know where you are. The private quarries are well-marked and charge a fee to dig, but they can almost guarantee you’ll find trilobites. Most state lands are administered by the Schools and Institutional Trust Lands Administration and require a rockhounding permit to collect on these lands. Head to their website to learn about current fees. A permit allows you to take up to 25 pounds of material daily plus one piece per person or 250 pounds per year.

BEST TIME TO VISIT
Most rockhounds consider spring and fall the best times for this activity. Being in the blistering summer sun or trying to extract from the frozen ground can turn a fun, rockhounding adventure into a miserable day. The desert is prone to flash flooding, so be diligent in checking the weather forecast as you plan your trip.
