The Snowville 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.
Snowville’s center stands about 4,560 ft above sea level. Within three miles the land runs from 4,510 ft to 5,480 ft, a difference of 970 ft: steep hill country. The highest named summit within 15 miles is Monument Peak, about 5,960 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Lake Bonneville deposits (clay), from the Pleistocene, 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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Age: Carboniferous to Permian, 252 to 324 million years old. About 6 mi of the line.
Basalt. Age: Pliocene, 2.6 to 5.3 million years old. About 4 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 33,000 years old. About 2 mi of the line.
Gravel. Age: Quaternary, less than 2.6 million years old. About 0.5 mi of the line.
