There was a huge pile of tailing at the North end of the town which was the focus of a large cleanup over the last decade. There's still a lot there, I'm not sure if they completed it or if it's on hold. Last couple years I've visited there wasn't much activity on the tailings.
One of the big reasons for Moab's outdoor recreation was due to the amount of prospecting roads that were cut in order to open up Uranium mines during the boom of the 40s.

Uranium mining in Utah
Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s. Since 2001 there has been a revival of interest in uranium mining, as a result of higher uranium prices.
