Bessemer Bend’s center stands about 5,240 ft above sea level. Within three miles the land runs from 5,170 ft to 6,760 ft, a difference of 1,590 ft: steep hill country. The highest named summit within 15 miles is Muddy Mountain, about 8,290 ft, 14 miles east-southeast.
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 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone. Age: Late Cretaceous, 78 to 83 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Cambrian to Permian, 252 to 542 million years old. About 4 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Granite. Age: Archean. About 3 mi of the line.
Sandstone, limestone. Age: Carboniferous to Permian, 252 to 324 million years old. About 2 mi of the line.
Claystone. Age: Eocene, 34 to 56 million years old. About 2 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 Bessemer Bend reaches the Gulf of America by way of the North Platte, the Platte, the Missouri and the Mississippi: about 2,510 river miles.
1,170 miles of the trip are on the Mississippi.

Bessemer Bend has a warm-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 15° in January. A normal year brings about 72 inches of snow; with the rain, that comes to about 12 inches of water.
On November 14 Bessemer Bend normally reaches 47° and falls to 23°. The record high is 68°, in 1999; the record low −10°, in 1978. The most rain on this date, 0.40 in, fell in 2006.
