Shoshone’s center stands about 1,580 ft above sea level. Within three miles the land runs from 1,430 ft to 2,730 ft, a difference of 1,300 ft: steep hill country. The highest named summit within 15 miles is Nopah Peak, about 6,320 ft, 11 miles east-northeast.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.
Rhyolite, basalt. Age: Early Miocene to Early Pliocene, 4 to 22 million years old. About 4 mi of the line.
Sandstone, dolostone. Age: Neoproterozoic to Middle Devonian, 384 to 1,000 million years old. About 4 mi of the line.
Dolostone, limestone. Age: Ordovician to Early Devonian, 394 to 487 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Shoshone reaches the desert basins of Owens Valley and Death Valley by way of the Amargosa: about 85 river miles. The desert basins of Owens Valley and Death Valley has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Often dry. About 100% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shoshone; river miles along the main stem, rounded.
