83° on Nov. 16, 2016, the hottest reading for this week of the year since 1967. Next is 80° in 1999.
Kersey’s center stands about 4,620 ft above sea level. Within three miles the land runs from 4,570 ft to 4,790 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Point of Rocks, about 4,970 ft, 13 miles east-northeast.
Under the town center the state geologic map shows Gravels and alluviums (gravel, unconsolidated), from the Pleistocene, less than 0.5 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, silt. Age: Quaternary, less than 2.6 million years old. About 12 mi of the line.
Gravel, unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 6 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 5 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 Kersey reaches the Gulf of America by way of the South Platte, the Platte, the Missouri and the Mississippi: about 2,330 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kersey; river miles along the main stem, rounded.
Kersey has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 18° in January. A normal year brings about 35 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 Kersey normally reaches 54° and falls to 26°. The record high is 78°, in 2025; the record low 4°, in 2014. The most rain on this date, 0.50 in, fell in 1993.
Normals 1991–2020 and records since 1967 at Greeley Unc, 7 miles west, 140 ft higher. NOAA, through RCC-ACIS.
