Under the town center the state geologic map shows Black Hand Sandstone Member of Cuyahoga Formation (sandstone, conglomerate), from the Carboniferous, 324 to 359 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 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.
Sandstone, conglomerate. Age: Carboniferous, 324 to 359 million years old. About 15 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 9 mi of the line.

A raindrop that lands in Hamburg reaches the Gulf of America by way of Muddy Prairie Run, Clear Creek, the Hocking, the Ohio and the Mississippi: about 1,830 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 Hamburg; river miles along the main stem, rounded.
