65° on Nov. 15, 2016, the hottest reading for this week of the year since 1990. Next is 64° in 1999.
Diamondville’s center stands about 6,880 ft above sea level. Within three miles the land runs from 6,820 ft to 7,690 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Quealy Peak, about 8,010 ft, 5 miles north-northeast.
Under the town center the state geologic map shows Frontier Formation (shale, sandstone), from the Late Cretaceous, 66 to 100 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 15×. 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, shale. Age: Late Cretaceous, 66 to 100 million years old. About 12 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Mudstone, sandstone, conglomerate. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Black-shale, sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Shale, siltstone. Age: Early Cretaceous, 100 to 145 million years old. About 1 mi of the line.
Siltstone, sandstone, limestone. Age: Middle Jurassic to Late Jurassic, 145 to 175 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.

A raindrop that lands in Diamondville reaches the Gulf of California by way of the Hams Fork, the Blacks Fork, the Green River and the Colorado: about 1,610 river miles.
Lakes on the way: Lake Mead, Lake Powell, Flaming Gorge Reservoir and Lake Mohave.
410 miles of the trip are on the Green River.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.

Diamondville has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 2° in January. A normal year brings about 50 inches of snow; with the rain, that comes to about 9 inches of water.
On November 14 Diamondville normally reaches 43° and falls to 14°. The record high is 64°, in 1999; the record low 0°, in 2009. The most rain on this date, 0.22 in, fell in 2006.
Normals 1991–2020 and records since 1990 at Kemmerer 2 N, 3 miles north. NOAA, through RCC-ACIS.
