The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 19 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 0.7 mi of the line.
