Converse’s center stands about 830 ft above sea level. Within three miles the land runs from 790 ft to 850 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Wabash Formation (limestone, dolostone), from the Silurian, 422 to 445 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.
Limestone, dolostone. Age: Silurian, 422 to 445 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
