Old Dad Mountain is a summit, southwest of the Cinder Cone Lava Beds, west of the Kelso Mountains, north of Jackass Canyon, northeast of the Devils Playground and east of Soda Lake, in San Bernardino County, California. Old Dad Mountain was named in humorous contrast to the nearby Old Woman Mountains.[4]
