The Apple Valley plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Apple Valley’s center stands about 2,950 ft above sea level. Within three miles the land runs from 2,860 ft to 3,020 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is White Mountain, about 7,700 ft, 15 miles southeast.
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 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. 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 10 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 7 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 5 mi of the line.
Marble. Age: Neoproterozoic to Carboniferous, 299 to 1,000 million years old. About 2 mi of the line.

Rain that falls on Apple Valley runs straight into the desert basins of Owens Valley and Death Valley. 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.
