The Harold Formation is a geologic formation in the Central Mojave Desert, west of Victorville and north of the San Gabriel Mountains, in eastern San Bernardino County, Southern California.[http://www.quake.ca.gov/gmaps/RGM/sanbernardino/sanbernardino.html Quake.ca.gov: Geologic Map of the San Bernardino Quadrangle], California Geological Survey.
Geology
The formation, with Shoemaker Gravel in other areas, overlies the Pliocene epoch Crowder Formation.[https://thesis.library.caltech.edu/282/ Caltech Thesis: "Neotectonics of the north frontal fault system of the San Bernardino Mountains, southern California : Cajon Pass to Lucerne Valley"], Meisling, Kristian Erik (1984), Dissertation (Ph.D.), California Institute of Technology.
