West Peoria’s center stands about 600 ft above sea level. Within three miles the land runs from 430 ft to 710 ft, a difference of 280 ft: rolling country.
Under the town center the state geologic map shows Carbondale Formation (shale, sandstone, coal), from the Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old.
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 49×. 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, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 14 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 10 mi of the line.
