|Location and accuracy||This occurrence is approximately located, possibly within two miles. According to the original description (Sainsbury, 1975, p. 92-93), malachite in dolomite occurs in the headwaters of Copper Creek. Copper Creek is an east-flowing drainage with headwaters on the ridge east of Camp Haven (Death Valley). The location used here differs from that of Gamble (1988; locality 39).|
Geologic descriptionSainsbury (1975, p. 92-93) very briefly describes this occurrence as schistose limestone, almost completely converted to dolomite, that carries visible malachite. The geologic map of the area (Till and others, 1986) shows Paleozoic marble on both sides of upper Copper Creek.
