−6° on Nov. 17, 1959, the coldest reading for this week of the year since 1899. Next is −2° in 1986.
Quinnesec’s center stands about 1,040 ft above sea level. Within three miles the land runs from 920 ft to 1,500 ft, a difference of 580 ft: hilly country. The highest named summit within 15 miles is Millie Hill, about 1,590 ft, 3 miles west-northwest.
Under the town center the state geologic map shows Baraga Group; Michigamme Formation, undivided (mixed-clastic, metagraywacke), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt, basaltic-andesite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 7 mi of the line.
Mixed-clastic, metagraywacke. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
Gneiss, amphibolite, migmatite. Age: Paleoarchean to Neoarchean, 2.5 to 3.6 billion years old. About 2 mi of the line.
Metasedimentary, metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Granite, tonalite, gneiss. Age: Paleoproterozoic, 1.8 to 1.9 billion years old. About 2 mi of the line.
Greenstone, basalt. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Quinnesec reaches Lake Michigan by way of the Menominee: about 90 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

Quinnesec has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 4° in January. A normal year brings about 61 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Quinnesec normally reaches 41° and falls to 25°. The record high is 70°, in 1999; the record low 2°, in 1986. The most rain on this date, 0.92 in, fell in 2000.
Normals 1991–2020 and records since 1899 at Iron Mtn-Kingsford Wwtp, 4 miles west-southwest. NOAA, through RCC-ACIS.
