−22° on Nov. 14, 1940, the coldest reading for this week of the year since 1929. Next is −16° in 1955.
Ryder’s center stands about 2,100 ft above sea level. Within three miles the land runs from 2,070 ft to 2,140 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Blue Hill, about 2,260 ft, 11 miles south.
Under the town center the state geologic map shows Sentinel Butte Formation (siltstone, claystone, sandstone), from the Paleocene, 56 to 66 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, claystone, sandstone. Age: Paleocene, 56 to 66 million years old. About 23 mi of the line.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 0.8 mi of the line.

Ryder has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 0° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Ryder normally reaches 36° and falls to 18°. The record high is 72°, in 1939; the record low −22°, in 1940. The most rain on this date, 0.40 in, fell in 1944.
Normals 1991–2020 and records since 1929 at Max, 19 miles east-southeast. NOAA, through RCC-ACIS.
