The Wolbach plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
82° on Nov. 15, 2025, the hottest reading for this week of the year since 1894. Next is 80° in 1956.
Wolbach’s center stands about 1,910 ft above sea level. Within three miles the land runs from 1,820 ft to 2,060 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. 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-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 24 mi of the line.

A raindrop that lands in Wolbach reaches the Gulf of America by way of Spring Creek, the Loup, the Platte, the Missouri and the Mississippi: about 1,940 river miles.
1,170 miles of the trip are on the Mississippi.

Wolbach has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 10° in January. A normal year brings about 30 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Wolbach normally reaches 50° and falls to 23°. The record high is 73°, in 2025; the record low −9°, in 1986. The most rain on this date, 0.22 in, fell in 1968.
