Roderfield’s center stands about 1,550 ft above sea level. Within three miles the land runs from 1,110 ft to 2,230 ft, a difference of 1,120 ft: steep hill country. The highest named summit within 15 miles is Shawnee Mountain, about 2,810 ft, 15 miles east-southeast.
Under the town center the state geologic map shows New River Formation (sandstone), from the Carboniferous, 299 to 324 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 14×. 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. Age: Carboniferous, 299 to 324 million years old. About 24 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.

Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Roderfield reaches the Gulf of America by way of the Tug Fork, 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 Roderfield; river miles along the main stem, rounded.
