−3° on Nov. 16, 1955, the coldest reading for this week of the year since 1893. Next is −3° in 2012.
Center’s center stands about 7,650 ft above sea level. Within three miles the land runs from 7,610 ft to 7,680 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Eagle Rock, about 9,450 ft, 15 miles west-northwest.
Under the town center the state geologic map shows Unclassified surficial deposits and underlying Alamosa Fm in San Luis Valley (unconsolidated), from the Tertiary to Quaternary, less than 66 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 36×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Unconsolidated. Age: Tertiary to Quaternary, less than 66 million years old. About 22 mi of the line.
Gravel, unconsolidated. Age: Pleistocene, 0.2 to 1.6 million years old. About 1 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 0.7 mi of the line.
Volcanic. Age: Oligocene, 23 to 34 million years old. About 0.6 mi of the line.

Center has a cold semi-arid climate. Summer afternoons average 81° in July; winter nights fall to about 7° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 10 inches of water.
On November 14 Center normally reaches 49° and falls to 18°. The record high is 65°, in 1999; the record low 0°, in 1940. The most rain on this date, 0.80 in, fell in 1993.
