−9° on Nov. 16, 1932, the coldest reading for this week of the year since 1893. Next is −6° in 1933.
Summit’s center stands about 1,610 ft above sea level. Within three miles the land runs from 1,530 ft to 1,670 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Lookout Mountain, about 1,960 ft, 7 miles northwest.
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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. 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 14 mi of the line.
Basalt, basaltic-andesite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 9 mi of the line.
Rhyolite, dacite. Age: Paleoproterozoic, 1.8 to 1.8 billion years old. About 1 mi of the line.

A raindrop that lands in Summit reaches the Gulf of America by way of the North Branch Pine, the Pine River, the Wisconsin and the Mississippi: about 1,920 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; river miles along the main stem, rounded.
Summit 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 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.
Normals 1991–2020 and records since 1893 from the Rhinelander Area threaded record (Rhinelander Oneida County Airport, 21 miles north-northwest). NOAA, through RCC-ACIS.
