'''Red Slate Mountain''' is a summit in the [[Sierra Nevada (U.S.)|Sierra Nevada]]. It lies along the [[Sierra Crest]] that divides [[Fresno County, California|Fresno County]] from [[Mono County, California]].
Red Slate Mountain can be reached by scrambling either from [[McGee Pass]], or starting from [[Bighorn Lake (California)|Bighorn Lake]].
The area to the north of Red Slate Mountain is among the most seismically active in California which is associated with the [[Long Valley Caldera]].
Red Slate Mountain was named by the [[California Geological Survey]], in 1873. However, it is not clear whether the survey meant to name this peak, or [[Red and White Mountain]].<ref name="Farquhar"/>
