Geology & Origin
The Monument #2 Mine is one of the best-known uranium deposits of the Colorado Plateau and was extensively mined during the 1950s. Uranium mineralisation formed within porous sandstone together with vanadium and other associated elements. Rauvite, Coffinite and other secondary uranium minerals occur in complex mineral assemblages, making this locality a classic source highly valued by mineral collectors.
