71° on Nov. 14, 1999, the hottest reading for this week of the year since 1948. Next is 69° in 1990.
Sheridan’s center stands about 990 ft above sea level. Within three miles the land runs from 970 ft to 1,230 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Otteson Bluff, about 1,280 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 52×. 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. Age: Cambrian, 487 to 542 million years old. About 24 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 Sheridan reaches the Gulf of America by way of the Hay, the Red Cedar, the Chippewa and the Mississippi: about 1,820 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sheridan; river miles along the main stem, rounded.
Sheridan has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 2° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Sheridan normally reaches 41° and falls to 24°. The record high is 71°, in 1999; the record low 3°, in 1996. The most rain on this date, 1.00 in, fell in 2010.
