The Barnesville 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.
Barnesville’s center stands about 1,250 ft above sea level. Within three miles the land runs from 1,000 ft to 1,330 ft, a difference of 330 ft: rolling country.
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 37×. 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 11 mi of the line.
Mudstone, shale, siltstone. Age: Carboniferous to Permian, 252 to 324 million years old. About 8 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.

A raindrop that lands in Barnesville reaches the Gulf of America by way of Spencer Creek, Stillwater Creek, the Tuscarawas, the Muskingum, the Ohio and the Mississippi: about 1,990 river miles.
970 miles of the trip are on the Mississippi.
