The butte lies approximately 22 miles (35 km) 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.

[2] Some noteworthy minerals from the Castle Dome Mountains region are vanadinite, wulfenite, baryte, and fluorite.
