Mariah Hill’s center stands about 540 ft above sea level. Within three miles the land runs from 420 ft to 610 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Raccoon Creek Group (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 24 mi of the line.
