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.

Famous quotes containing the words white, canyon, monument, valley and/or districts:
“The birch stripped of its bark, or the charred stump where a tree has been burned down to be made into a canoe,—these are the only traces of man, a fabulous wild man to us. On either side, the primeval forest stretches away uninterrupted to Canada, or to the “South Sea”; to the white man a drear and howling wilderness, but to the Indian a home, adapted to his nature, and cheerful as the smile of the Great Spirit.”
—Henry David Thoreau (1817–1862)
“In a world that holds books and babies and canyon trails, why should one condemn oneself to live day-in, day-out with people one does not like, and sell oneself to chaperone and correct them?”
—Ruth Benedict (1887–1948)
“If a man do not erect in this age his own tomb ere he dies, he shall live no longer in monument than the bell rings and the widow weeps.”
—William Shakespeare (1564–1616)
“All the Valley quivered one extended motion, wind
undulating on mossy hills”
—Allen Ginsberg (b. 1926)
“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)
