(Syn: Fourth of July Canyon)

See also: New York Mountains.

See also: Giant Ledge Mine.

Formerly known as Fourth of July Canyon (1920, 1921, 1940).

There is some thought that "Caruthers" should be spelled with two r's as "Carruthers," assuming that the canyon is named for George Carruthers, watchman at the Giant Ledge mine (Sharp, 1984). This is apparently noted in book by Ausmus and Casebier. Also, Figure 17 on page 21 of Reynolds and Reynolds (1995) implies that Carruthers may be an alternate spelling of Caruthers. However, Caruthers seems to be the adopted spelling for use on maps, etc.

Elevation: 5230ft, 1594m.
