Greenville’s center stands about 820 ft above sea level. Within three miles the land runs from 780 ft to 930 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Mosquito Hill, about 1,010 ft, 10 miles northwest.
Under the town center the state geologic map shows Ancell Group (sandstone), from the Ordovician, 445 to 487 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 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.

A raindrop that lands in Greenville reaches Lake Michigan by way of the Rat, the Wolf River and the Fox River: about 100 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124, Lake Winneconne and Lake Butte des Morts.
