Summit Lake’s center stands about 1,700 ft above sea level. Within three miles the land runs from 1,580 ft to 1,770 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Lookout Mountain, about 1,960 ft, 14 miles west.
Under the town center the state geologic map shows Mafic to felsic metavolcanic rocks, from the Paleoproterozoic, 1.6 to 2.5 billion 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.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 19 mi of the line.
Basalt, basaltic-andesite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Summit Lake reaches the Gulf of America by way of the East Branch Eau Claire, the Eau Claire, the Wisconsin and the Mississippi: about 1,940 river miles.
Lakes on the way: Petenwell Lake, Lake Wisconsin, Lake Du Bay and Wisconsin River Flowage 4964.
1,610 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Summit Lake; river miles along the main stem, rounded.
Summit Lake has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 4° in January. About 30 inches of rain fall in a normal year.
On November 14 Summit Lake normally reaches 40° and falls to 23°. The record high is 63°, in 1953; the record low −3°, in 1916. The most rain on this date, 0.49 in, fell in 1930.
