The Darwin 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.
Darwin’s center stands about 4,830 ft above sea level. Within three miles the land runs from 3,690 ft to 5,640 ft, a difference of 1,950 ft: steep hill country. The highest named summit within 15 miles is Maturango Peak, about 8,770 ft, 12 miles south-southeast.
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 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. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 8 mi of the line.
Sandstone, limestone. Age: Carboniferous to Triassic, 202 to 324 million years old. About 5 mi of the line.
Limestone. Age: Carboniferous to Permian, 273 to 359 million years old. About 1 mi of the line.

A raindrop that lands in Darwin reaches the desert basins of Owens Valley and Death Valley by way of Lucky Jim Wash and Darwin Wash: about 20 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.
