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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Middle Miocene, 12 to 14 million years old. About 13 mi of the line.
Clay, sand. Age: Early Miocene to Middle Miocene, 14 to 20 million years old. About 3 mi of the line.
