Castle Dome (butte)

Castle Dome, or Castle Dome Peak is a prominent butte and high point of the Castle Dome Mountains northeast of Yuma, Arizona, in the northwestern Sonoran Desert.

The butte lies approximately 22 mi east of the historical Castle Dome Landing on the Colorado River (site submerged by the Imperial Reservoir). It is located above and east of US Route 95 and the Castle Dome mining district. Castle Dome is noteworthy for its recreational use for day hiking. It is also often coated in winter or spring snowstorms as a white landform, with its loss of white being determined by season and duration of storm temperatures. Castle Dome's height is 3791 ft.
