A former Au-Ag placer mining area located in the NW¼ T8S, R19W & the NE¼ T8S, R20W.
Mineralization is spotty gold nuggets and particles in ancient bars in thick, cemented conglomerate, intercalated with Cretaceous rhyolitic lava flows, and in streak beds draining South and SW from Klothos Temple (Coronation Peak), Long Mountain, and the Muggins Peak. The gold probably was derived from gold-bearing quartz veins in Mesozoic metamorphic gneiss, schist, and granite exposed in the northwestern part of the range.
Workings were sporadic placer operations from the 1860's, in numerous washes and canyons, with the main production probably prior to 1900.
