Muskego’s center stands about 810 ft above sea level. Within three miles the land runs from 760 ft to 1,000 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 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 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Silurian, 422 to 445 million years old. About 20 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.

A raindrop that lands in Muskego reaches the Gulf of America by way of the Muskego Canal, the Fox River, the Illinois and the Mississippi: about 1,580 river miles.
Lakes on the way: Peoria Lake and Fox Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Muskego; river miles along the main stem, rounded.
Muskego has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 17° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Muskego normally reaches 48° and falls to 34°. The record high is 70°, in 1971; the record low 7°, in 1959. The most rain on this date, 1.24 in, fell in 1926.
