Shirley Mountain Road
Abandoned uranium mines meet technical rock crawling
The Shirley Mountains hide one of Wyoming’s forgotten uranium booms, where Pathfinder Mines once operated the Lucky Mc deposit. Forest Road 101 climbs from sage flats into dense timber, passing rusted machinery and reclaimed mine sites. The route peaks at Shirley Lake, surrounded by granite outcrops that demand careful tire placement. Technical sections include loose talus fields and exposed bedrock that’ll test both driver skill and vehicle protection.
This is expert territory requiring lockers, skid plates, and recovery gear. Summer thunderstorms turn exposed ridges dangerous, while winter access is impossible above 8,000 feet. Water is scarce—pack extra. The payoff is complete solitude in country that sees maybe a dozen vehicles per month. Best attempted July through September with a spotter for the worst sections. Camping is unlimited on Forest Service land, but pack out everything.
