An occurrence located in sec. 22, T2S, R3E, SBM, 7.7 km (4.8 miles) NNW of Whitewater (town), along the W canyon wall of the Whitewater River, W of the Whitewater Trout farm.
Piemontite-bearing gneiss, forming part of a pre-Cretaceous metamorphic complex which crops out in the southern foothills of the San Bernardino Mountains. Along the Banning fault, which trends E-W along the north side of San Gorgonio pass, this complex is thrust over Pliocene and Pleistocene sedimentary and volcanic rocks. The gneisses crop out in the area North of this fault.
While the article cited below vaguely refers to the locality as San Gorgonio pass, the article deals with two specific outcrops. The one described here is located on the west side of the Whitewater River. The other outcrop is located further West within the Morongo Indian Reservation, about 0.6 miles West of Stubby Canyon. Boulders of piemontite-bearing gneiss also occur in Pliocene conglomerate in the Painted Hills, east of the Whitewater river.
The piemontite gneiss and associated epidote gneiss are light-colored rocks which form a layered zone within the metamorphic complex. The typical rock in the surrounding area is a dark-colored hornblende-biotite gneiss. About 75-80% of the piemontite gneiss consists of quartz, plagioclase and microcline; the remainder consists of piemontite, mica, amphibole, pyroxene, garnet and hematite in varied proportions. Bright red piemontite-rich layers and pods are prominent features. Pegmatitic lenses, layers and dykes are common, but usually only some inches long. They contain all the minerals of the gneisses and also up to 25% of ilmenite.
