66° on Nov. 17, 1999, the hottest reading for this week of the year since 1897. Next is 65° in 1962.
Wamsutter’s center stands about 6,710 ft above sea level. Within three miles the land runs from 6,670 ft to 6,920 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Big Hill, about 7,050 ft, 3 miles south-southwest.
Under the town center the state geologic map shows Wasatch Formation - Main Body (claystone, siltstone), from the Paleocene to Eocene, 34 to 66 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 30×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, siltstone. Age: Paleocene to Eocene, 34 to 66 million years old. About 12 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Oil-shale, marlstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Oil-shale, marlstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Gravel. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Clay, silt, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 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.

Wamsutter has a cold semi-arid climate. Summer afternoons average 85° in July; winter nights fall to about 9° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 8 inches of water.
On November 14 Wamsutter normally reaches 43° and falls to 19°. The record high is 62°, in 1999; the record low −8°, in 1978. The most rain on this date, 0.26 in, fell in 1964.
