66° on Nov. 13, 1999, the hottest reading for this week of the year since 1961. Next is 65° in 2001.
Michigamme’s center stands about 1,640 ft above sea level. Within three miles the land runs from 1,550 ft to 1,780 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Baraga Group; Michigamme Formation; Gray to black slate, from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mixed-clastic, metagraywacke. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 12 mi of the line.
Gneiss, amphibolite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 mi of the line.
Slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Quartzite, slate, banded-iron-formation. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 1 mi of the line.
Metasedimentary, metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 1.0 mi of the line.

A raindrop that lands in Michigamme reaches Lake Michigan by way of Lake Michigamme, the Michigamme and the Menominee: about 190 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: Michigamme Reservoir and Lake Michigamme.
120 miles of the trip are on the Menominee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Michigamme; river miles along the main stem, rounded.
Michigamme has a warm-summer humid continental climate. Summer afternoons average 76° in July; winter nights fall to about 7° in January. A normal year brings about 197 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Michigamme normally reaches 38° and falls to 25°. The record high is 59°, in 2001; the record low 5°, in 1995. The most rain on this date, 0.51 in, fell in 2020.
