Goodsprings’s center stands about 3,730 ft above sea level. Within three miles the land runs from 3,330 ft to 5,040 ft, a difference of 1,710 ft: steep hill country. The highest named summit within 15 miles is Potosi Mountain, about 8,460 ft, 10 miles north-northwest.
Under the town center the state geologic map shows Alluvium, undifferentiated (coarse-detrital, fine-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. 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, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.
Limestone, dolostone, siltstone. Age: Carboniferous to Permian, 273 to 324 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Cambrian to Middle Devonian, 384 to 497 million years old. About 3 mi of the line.
Limestone. Age: Middle Devonian to Late Devonian, 359 to 394 million years old. About 1 mi of the line.
Siltstone, limestone, conglomerate. Age: Early Triassic to Middle Triassic, 237 to 252 million years old. About 1 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
