Under the town center the state geologic map shows Surficial Deposits, Undivided (sand, clay, gravel), from the Quaternary, less than 2.6 million years old.
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.
