−1° on Nov. 17, 1969, the coldest reading for this week of the year since 1894. Next is 0° in 1955.
Rangely’s center stands about 5,230 ft above sea level. Within three miles the land runs from 5,180 ft to 5,760 ft, a difference of 580 ft: hilly country. The highest named summit within 15 miles is Red Hill, about 7,900 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Mancos Shale (shale, sandstone), from the Early Cretaceous to Late Cretaceous, 66 to 145 million years old.
The section below crosses 6 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.
Sandstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 7 mi of the line.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Shale, sandstone, marlstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Claystone. Age: Paleocene to Eocene, 34 to 66 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Rangely reaches the Gulf of California by way of the White River, the Green River and the Colorado: about 1,330 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.

Rangely has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 3° in January. A normal year brings about 30 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Rangely normally reaches 49° and falls to 20°. The record high is 72°, in 1903; the record low 1°, in 1911. The most rain on this date, 0.32 in, fell in 1987.
Normals 1991–2020 and records since 1894 at Rangely 1 E, here. NOAA, through RCC-ACIS.
