Previously, the metamorphic rocks in the northeastern portion of the Alabama Hills were mapped as a single unit, (encompassing Triassic metasediments and metavolcanics). The following pre- metamorphic sequence is proposed to explain the patterns seen in the geologic map. Final stages in the formation of the present day expression of the Alabama Hills includes exhuming of a preglacial pediment surface as normal faulting uplifted the Alabama Hills block relative to the Owens Valley. The Alabama Hills were the draped with glacial outwash debris of Sherwin, Tahoe, and Tiogan glacial ages. As recently as 1872 (1872 Owens Valley Earthquake) the expression of the Alabama Hills has been modified by tectonic forces.
