Location: Ventura County, California

Name derived from William B. Whitacre, an area pioneer who homesteaded 80 acres by Devil's Pothole, near this peak (1891). A relative, Thomas Whitaker homesteaded the 160 acre ranch still shown on most maps along Piru Creek (1891), and for whom Whitaker Peak was named. Both summits appear on maps at the same time. The shift in spelling was probably a draftsman's device to avoid confusing the two peaks.

Delisted from HPS Peak List when it was proposed as part of the Sespe Condor Sanctuary and before access was forbidden (1959).

Name first appears on USGS Tejon quad (1903).

Peak was on the original 1946 HPS Peak List.
