The Liverpool plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Liverpool’s center stands about 450 ft above sea level. Within three miles the land runs from 420 ft to 590 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Tampico Mounds, about 610 ft, 2 miles north-northwest.
The section below crosses 3 rock units mapped at the surface.
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.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 11 mi of the line.
Limestone. Age: Middle Mississippian, 331 to 347 million years old. About 8 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 5 mi of the line.

A raindrop that lands in Liverpool reaches the Gulf of America by way of the Illinois and the Mississippi: about 1,320 river miles.
