White Canyon and Monument Valley Districts
Uranium associated with copper mineralization at the White Canyon district in was identified in 1920, but production did not begin until 1946. The geology is similar to that of the Monument Valley uranium district 40 miles to the south which straddles the Utah/Arizona state line (see Uranium mining in Arizona). Uranium occurs in the Shinarump Member of the Triassic Chinle Formation. Primary ore minerals are uraninite and coffinite. Through 1965, the White Canyon district produced 10 million pounds of U3O8. On June 29, 2012, Energy Fuels acquired the Daneros mine from Denison Mines in Utah's White Canyon District. Energy Fuels produced from the Daneros mine until October 2012, at which time the mine was placed on standby, care, and maintenance.

“Cities need old buildings so badly it is probably impossible for vigorous streets and districts to grow without them.... for really new ideas of any kind—no matter how ultimately profitable or otherwise successful some of them might prove to be—there is no leeway for such chancy trial, error and experimentation in the high-overhead economy of new construction. Old ideas can sometimes use new buildings. New ideas must use old buildings.”
—Jane Jacobs (b. 1916)
