Bucyrus’s center stands about 2,780 ft above sea level. Within three miles the land runs from 2,730 ft to 3,010 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Wolf Butte, about 3,020 ft, 6 miles north.
Under the town center the state geologic map shows Slope Formation (sandstone, siltstone, claystone), from the Paleocene, 56 to 66 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 47×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 13 mi of the line.
Sandstone, siltstone, claystone. Age: Paleocene, 56 to 66 million years old. About 8 mi of the line.
Siltstone, claystone, sandstone. Age: Paleocene, 56 to 66 million years old. About 1 mi of the line.
Sandstone, claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 0.8 mi of the line.
Sandstone. Age: Paleocene, 56 to 66 million years old. About 0.6 mi of the line.
Coarse-detrital, clay. Age: Quaternary, less than 2.6 million years old. About 0.2 mi of the line.

A raindrop that lands in Bucyrus reaches the Gulf of America by way of Flat Creek, the Grand River, the Missouri and the Mississippi: about 2,600 river miles.
Lakes on the way: Lake Oahe, Lake Sharpe, Lake Francis Case and Lewis and Clark Lake.
1,170 miles of the trip are on the Mississippi.

Bucyrus has a cold semi-arid climate. Summer afternoons average 84° in July; winter nights fall to about 5° in January. About 14 inches of rain fall in a normal year.
On November 14 Bucyrus normally reaches 42° and falls to 18°. The record high is 71°, in 2025; the record low −22°, in 2014. The most rain on this date, 0.03 in, fell in 2005.
Normals 1991–2020 and records since 1996 at Hettinger Municipal Airport, 8 miles east-southeast. NOAA, through RCC-ACIS.
