74° on Nov. 11, 2006, the hottest reading for this week of the year since 1944. Next is 71° in 1993.
Cass’s center stands about 2,630 ft above sea level. Within three miles the land runs from 2,410 ft to 4,700 ft, a difference of 2,290 ft: mountain country. The highest named summit within 15 miles is Bald Knob, about 4,860 ft, 4 miles north.
Under the town center the state geologic map shows Hampshire Formation (shale, sandstone), from the Devonian, 359 to 422 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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, shale. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 8 smaller units along the line are not listed.

A raindrop that lands in Cass reaches the Gulf of America by way of the Greenbrier, the New River, the Kanawha, the Ohio and the Mississippi: about 1,980 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cass; river miles along the main stem, rounded.
Cass has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 17° in January. A normal year brings about 67 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Cass normally reaches 49° and falls to 28°. The record high is 71°, in 1994; the record low 5°, in 1976. The most rain on this date, 1.70 in, fell in 1993.
Normals 1991–2020 and records since 1944 at Bartow 1 S, 12 miles northeast, 400 ft higher. NOAA, through RCC-ACIS.
