A former Cr occurrence/mine located in the SE¼NE¼ (assumed) sec. 29, T14N, R11E, MDM, 0.4 km (0.2 mile) WSW of Sage Hill, on the E canyon wall of Mad Canyon (W slope of Sage Hill), on National Forest land. Owned by Frank O. Smith (1918). MRDS database stated accuracy for this location is 1,000 meters. Probably worked out.
This is one of many Cr deposits/mines placed into a very large area termed the "Forest Hill Divide area" by Rynearson. That area is based on geological and topographic considerations versus mining districts and overlaps several defined districts. Those Cr occurrences within mining districts are listed under their respective districts, the remainder are listed under Rynearson’s "Forest Hill Divide area."
This deposit occurs in the easternmost of 3 sub-parallel belts of ultramafic rocks that trend northward across Placer County. Local rocks include ultramafic rocks, chiefly Mesozoic, unit 2 (Western Sierra Nevada and Klamath Mountains).
Production data are found in: Rynearson, Garn Arthur (1953), p. 200.
