/in /by

View of Tecopa Basin, the south end of the Amargosa Valley. From the top of Tecopa Peak, one gets a wonderful view of the south end of the Amargosa Valley. In the middleground lies Lake Tecopa, surrounded by Plio-Pliestocene lake bed deposits. The mountains in the background are the Resting Spring Range (closest) and the Nopah Range. Both consist of predominantly Cambrian rock that has been tilted and faulted during crustal extension.

Due to the high salinity and alkali content, Lake Albert is uninhabitable for fish. However, this environment is perfect for brine shrimp and as a result, the lake provides an excellent habitat for a variety of shore birds. (Image ID# 140621-103)

Panamint Valley in Death Valley National Park

Paleozoic rock is folded because of the Late Paleozoic-early Mesozoic compressional mountain-building; it is intruded by Jurassic age granitic rock, an early phase of Sierran magmatism that took place just to the west; the granitic rock is overlain by Late Cenozoic basalt flows, and everything is cut by a normal (extensional) fault.
