Quaker City’s center stands about 870 ft above sea level. Within three miles the land runs from 850 ft to 1,260 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Ranker Knob, about 1,270 ft, 12 miles south.
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 4 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 6 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Quaker City reaches the Gulf of America by way of Leatherwood Creek, Wills Creek, the Muskingum, the Ohio and the Mississippi: about 1,960 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 Quaker City; river miles along the main stem, rounded.
