File:Tamarack Peak (Carson Range, Nevada, USA).jpg
The Carson Range is composed of Cretaceous granite and granite-like rocks of the Sierra Nevada Batholith, a complex of large, cooled magma chambers under a series of ancient subduction zone stratovolcanoes. Metamorphosed roof pendant rocks are also present in the Carson Range. Magma intrusion during the Cretaceous cooked the pre-existing overlying rocks. Plus some volcanics of late Cenozoic age.
Locality: Tamarack Peak, Carson Range, northwest of the town of Carson City, far-southern Washoe County, far-western Nevada, USA
