Cuyamaca Peak (LO site), San Diego County, California,

Elevation = 6508 ft.

Located in Cuyamaca Rancho State Park

A view of the lookout in October 1970. There was a fire lookout structure on this mountain as early as 1935. It may have been rebuilt at one time since USGS surveyors report in 1975 that there were older concrete piers set inside the ones for this tower. I believe this tower was taken down in 1983.
The primary benchmark is missing but this Reference Mark #3 dated 1954 was found. Datasheet.
