Last Field Trip for 2015

Thomas Range, UT - Topaz Mountain and Dugway Geode Beds

Date: Oct 10-11, 2015

Leader: Robert Boehm (If you don't have his contact info, email the CMS Webmaster below left at the Send CMS an E-mail link)

What to collect: Topaz, Red Beryl, Bixbyite, Pseudobrookite, Garnet, Pale Amethyst, Hematite and Geodes

If you want to go out early, contact the trip leader to coordinate before the week of the trip.

Meeting: Meet on Saturday the 10th at 9:00 AM at the turnoff from highway 174 leading to the ‘cove” (see
map). There should be a sign saying topaz mountain rockhounding area. Anyone arriving late on Saturday
should drive into the cove and take the west fork, leading toward the west wall, and look for a white Tacoma
pickup with a white topper. Sunday we will go to the geode beds on the north end of the range.

Travel Time: Approximately 12 hours from Denver and 1 hour from Delta.

Directions: From Delta, UT, go northeast on US 6 and for about 10 miles to Highway 174. Turn left and
follow Highway 174 west for about 37 miles. As you head west you’ll see mountains in the distance. Once you
turn northwest, topaz mountain will be directly in front of you. The turnoff to the cove should be just before
entering a group of small hills and you will see the circular shape of the cove below the highest point of the
mountain. If you go to the end of the pavement you have gone too far.

Essentials: water, sunscreen, hat, food

Tools: crack hammer, chisels, pry bar, probe, rock pick, garden trowel, 1/8” screen.

Hazards: remote location, heat, scorpions, black widows, tarantulas and possibly rattlesnakes.

Environment: Remote, arid, desert. Scrub covered rhyolite mountains surrounded by salt flats.

Vehicle: Any vehicle can make it to the base of the range. High clearance and 4 wheel drive may be needed in
the cove and in other locations. ATV’s greatly improve mobility.

Comments: Plenty of primitive campsites. Some hiking is necessary to reach the best spots, but faded topaz
can be found close to roads. For those going out early we can visit the west side of the Thomas Range, the
garnet basins, Maynard pit (reclaimed) or the best pseudobrookite locale. You are free to collect on BLM land.

There are active claims in the cove and other places.
