Topaz Ranch Estates’s center stands about 5,120 ft above sea level. Within three miles the land runs from 4,960 ft to 7,340 ft, a difference of 2,380 ft: mountain country. The highest named summit within 15 miles is Mount Siegel, about 9,430 ft, 11 miles north.
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 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. 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 6 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Andesite, dacite. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.
Volcanic, carbonate, clastic. Age: Middle Triassic to Middle Jurassic, 164 to 247 million years old. About 3 mi of the line.
Granitic, granodiorite, quartz-monzonite. Age: Jurassic to Miocene, 5.3 to 202 million years old. About 3 mi of the line.
Granodiorite, granite. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Topaz Ranch Estates reaches Walker Lake by way of the West Walker and the Walker: about 100 river miles. Walker Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
55 miles of the trip are on the Walker.
