Auburn’s center stands about 640 ft above sea level. Within three miles the land runs from 600 ft to 800 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Pilot Knob, about 950 ft, 3 miles south-southeast.
Under the town center the state geologic map shows Rocks of Chesterian age, lower part (limestone, sandstone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 14 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Auburn reaches the Gulf of America by way of Black Lick Creek, Clear Fork Creek, the Barren, the Green River, the Ohio and the Mississippi: about 1,360 river miles.
970 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 humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 26° in January. About 54 inches of rain fall in a normal year.
On November 14 Auburn normally reaches 58° and falls to 36°. The record high is 79°, in 1978; the record low 10°, in 2019. The most rain on this date, 2.31 in, fell in 1957.
Normals 1991–2020 and records since 1893 at Russellville, 10 miles west. NOAA, through RCC-ACIS.
