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 63×. 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, graywacke. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
