A former Cr occurrence/mine located in the center S½NE¼ (assumed) sec. 30, T15N, R11E, MDM, about 3.2 km N of Hughes Mill, on the S side of Pagge Creek and the E side of Finning Mill Road, on National Forest land. Operated by R. L. Turner and C. A. Geisendorfer (1919). MRDS database stated accuracy for this location is 1,000 meters. Other workings were located in secs. 20, 31 & 32, and in sec. 5, T14N, R11E. The concentrator was located in the SW¼SE¼ sec. 30.
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."
Local rocks include ultramafic rocks, chiefly Mesozoic, unit 2 (Western Sierra Nevada and Klamath Mountains).
Production data are found in: Rynearson, Garn Arthur (1953): 202-203.
