The area of the Slick Rock district saw the first production of uranium on the Colorado Plateau. Four periods of mining followed, initially for uranium from about 1900 to 1910, then for radium to about 1923. Following a decade of inactivity, mining resumed, this time for recovery of vanadium, in the early 1930s until 1944. Mining began again in 1949 for major production of uranium, with vanadium as a byproduct. This period lasted until 1983, ending when the price of uranium went into serious decline. Presently (2008) renewed interest in demand for uranium is pointing toward additional mining in the district.
