New Athens’s center stands about 400 ft above sea level. Within three miles the land runs from 370 ft to 470 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Turkey Hill, about 610 ft, 10 miles north.
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 64×. 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: Late Pennsylvanian, 304 to 307 million years old. About 12 mi of the line.
Limestone, sandstone, shale. Age: Middle Mississippian, 331 to 347 million years old. About 7 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 5 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 0.4 mi of the line.

A raindrop that lands in New Athens reaches the Gulf of America by way of the Kaskaskia and the Mississippi: about 1,120 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Athens; river miles along the main stem, rounded.
New Athens has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 24° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 New Athens normally reaches 59° and falls to 37°. The record high is 82°, in 1999; the record low 11°, in 1986. The most rain on this date, 3.23 in, fell in 1993.
