Adams’s center stands about 2,840 ft above sea level. Within three miles the land runs from 2,790 ft to 2,880 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Pleistocene and Pliocene deposits, undifferentiated (fine-detrital, coarse-detrital), from the Pliocene to Pleistocene, less than 5.3 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 14 mi of the line.
Fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 8 mi of the line.
Fine-detrital, coarse-detrital. Age: Pliocene, 2.6 to 5.3 million years old. About 1 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
