73° on Nov. 11, 1999, the hottest reading for this week of the year since 1950. Next is 68° in 1953.
Kevin’s center stands about 3,330 ft above sea level. Within three miles the land runs from 3,310 ft to 3,440 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Jerusalem Rocks, about 3,670 ft, 15 miles north.
Under the town center the state geologic map shows Ferdig Member of Marias River Formation (shale), from the Late Cretaceous, 87 to 94 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 20×. 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, siltstone, mudstone. Age: Late Cretaceous, 66 to 84 million years old. About 7 mi of the line.
Shale, siltstone. Age: Late Cretaceous, 94 to 100 million years old. About 6 mi of the line.
Shale. Age: Late Cretaceous, 90 to 100 million years old. About 4 mi of the line.
Shale. Age: Late Cretaceous, 87 to 94 million years old. About 4 mi of the line.
Shale, limestone, dolostone. Age: Late Cretaceous, 84 to 90 million years old. About 3 mi of the line.
Sandstone, siltstone, shale. Age: Late Cretaceous, 72 to 87 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.

Kevin has a cold semi-arid climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 12 inches of water.
On November 14 Kevin normally reaches 42° and falls to 18°. The record high is 68°, in 2025; the record low −18°, in 2014. The most rain on this date, 0.09 in, fell in 2008.
Normals 1991–2020 and records since 1950 at Shelby, 17 miles south-southeast. NOAA, through RCC-ACIS.
