63° on Nov. 14, 1999, the hottest reading for this week of the year since 1939. Next is 63° in 2023.
Plum Lake’s center stands about 1,700 ft above sea level. Within three miles the land runs from 1,630 ft to 1,820 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Baraga Group; Michigamme Formation, undivided (metagraywacke), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagraywacke. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 15 mi of the line.
Basalt. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
Banded-iron-formation. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Biotite-schist. Age: Paleoproterozoic, 1.8 to 1.9 billion years old. About 0.8 mi of the line.

A raindrop that lands in Plum Lake reaches the Gulf of America by way of Plum Creek, the Saint Germain, Gilmore Creek, the Wisconsin and the Mississippi: about 2,000 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 Plum Lake; river miles along the main stem, rounded.
Plum Lake has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 2° in January. A normal year brings about 76 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Plum Lake normally reaches 39° and falls to 22°. The record high is 63°, in 1999; the record low 3°, in 2014. The most rain on this date, 0.75 in, fell in 2000.
Normals 1991–2020 and records since 1939 at Eagle River, 15 miles southeast. NOAA, through RCC-ACIS.
