Auburn’s center stands about 1,030 ft above sea level. Within three miles the land runs from 900 ft to 1,140 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Council Grove Group (shale, limestone), from the Permian, 252 to 299 million years old.
The section below crosses 4 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.
Shale, limestone. Age: Permian, 252 to 299 million years old. About 15 mi of the line.
Shale, limestone. Age: Permian, 252 to 299 million years old. About 5 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Auburn reaches the Gulf of America by way of Longs Creek, the Little Nemaha, the Missouri and the Mississippi: about 1,700 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Auburn; river miles along the main stem, rounded.
Auburn has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 14° in January. A normal year brings about 30 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Auburn normally reaches 52° and falls to 30°. The record high is 77°, in 1990; the record low 1°, in 1940. The most rain on this date, 2.55 in, fell in 1909.
Normals 1991–2020 and records since 1893 at Auburn 5 ESE, 5 miles east-southeast. NOAA, through RCC-ACIS.
