Location: Riverside County, California
Named by USGS Survey (1897-98). Origin of the name has never been revealed, but perhaps some foolishness was committed (or at least considered) there by the surveyors. Don McLain once tried altering the peak name to honor Botanist Francis Fultz, author of The Elfin Forest (1927). Fultz was not amused to be considered a worthy replacement for a folly and angrily declined the attribution.
Folly Peak first appears on USGS San Jacinto quad (1901).
Peak was added to the HPS Peak List in 1954.
