The Poison Strip/Yellow Cat uranium mining area is a unique place to get a view into the past. Uranium mining began here in the 1940's but took off in the mid-1950s. By the early 1960's, however, the demand dwindled as the market had been oversupplied. Although a relatively brief time in the history of the area, Uranium mining has left a lasting impression, and it is fascinating to visit the area and see what remains.
To reach the Lost Spring area, you will need to travel east on I-70 (~ 30 miles north of Moab). Go east on I-70 from Crescent Junction 11 miles to exit 193. The exit is signed Yellow Cat Exit.
From the wooden structure, wander the roads south. An old bus is a good landmark to head for. Look for piles of dirt in the area, as they usually signify mines. The mines themselves are dug into the sandstone layer just below your feet. It is amazing how many openings, and how close together they are in the area. As is evident by signs at a few of the mines, the claims are still being kept current in case mining in the area ever becomes profitable again.
The area west of the wooded structure, where the road turns north by the pond you passed on the way in, also has an interesting old car and several ruins to visit.
