Winchester’s center stands about 850 ft above sea level. Within three miles the land runs from 750 ft to 840 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Mosquito Hill, about 1,010 ft, 13 miles north.
Under the town center the state geologic map shows Prairie du Chien Group (dolostone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 2 rock units mapped at the surface.

Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 15 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 7 mi of the line.

A raindrop that lands in Winchester reaches Lake Michigan by way of the Rat, the Wolf River and the Fox River: about 90 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.
