Location: San Diego County, California

This unusual place name was coined by the USFS as a combination between "Oak" (Quercus) and "Manzanita" (Arctostaphylos manzanita) to indicate the unique abundance of such growth in the Cuyamaca area.

Gudde notes that there are over one hundred California locations named for the 38 species of Manzanita.

Name first appears on USFS Cleveland National Forest (Descanso District) map (1970).

Peak was added to the HPS Peak List in 1962.
