Auburn’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,110 ft to 1,280 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Dakata and Windrow Formations (sandstone, shale), from the Early Cretaceous to Late Cretaceous, 94 to 113 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. 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: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 19 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 5 mi of the line.

A raindrop that lands in Auburn reaches the Gulf of America by way of the North Raccoon, the Des Moines and the Mississippi: about 1,680 river miles.
Lake on the way: Roberts Creek.
1,330 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 83° in July; winter nights fall to about 8° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Auburn normally reaches 46° and falls to 25°. The record high is 75°, in 1999; the record low −10°, in 1959. The most rain on this date, 1.98 in, fell in 1926.
