The Athens plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Athens’s center stands about 710 ft above sea level. Within three miles the land runs from 620 ft to 1,010 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Peck Hill, about 1,100 ft, 13 miles west.
Under the town center the state geologic map shows Conemaugh Group (shale, siltstone, mudstone), from the Carboniferous, 299 to 324 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 42×. 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, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.

A raindrop that lands in Athens reaches the Gulf of America by way of the Hocking, the Ohio and the Mississippi: about 1,780 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 Athens; river miles along the main stem, rounded.
