Wallins Creek’s center stands about 1,140 ft above sea level. Within three miles the land runs from 1,120 ft to 2,790 ft, a difference of 1,670 ft: steep hill country. The highest named summit within 15 miles is Brush Mountain, about 3,390 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Breathitt Formation, lower part (shale, siltstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. 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. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Conglomerate. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Limestone. Age: Devonian to Carboniferous, 299 to 422 million years old. About 0.6 mi of the line.
Sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 0.5 mi of the line.

A raindrop that lands in Wallins Creek reaches the Gulf of America by way of the Cumberland, the Ohio and the Mississippi: about 1,710 river miles.
Lakes on the way: Bards Lake, Lake Cumberland and Cordell Hull Reservoir.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wallins Creek; river miles along the main stem, rounded.
