5° on Nov. 17, 1959, the coldest reading for this week of the year since 1898. Next is 11° in 1933.
Copemish’s center stands about 810 ft above sea level. Within three miles the land runs from 770 ft to 1,070 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Briar Hill, about 1,740 ft, 15 miles east-southeast.
Under the town center the state geologic map shows Ellsworth Shale, from the Late Devonian, 359 to 384 million 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 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.

A raindrop that lands in Copemish reaches Lake Michigan by way of Dutchman Creek, Bear Creek and the Manistee: about 45 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Copemish; river miles along the main stem, rounded.
Copemish has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 19° in January. A normal year brings about 93 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Copemish normally reaches 44° and falls to 33°. The record high is 62°, in 1964; the record low 12°, in 1933. The most rain on this date, 1.00 in, fell in 1916.
Normals 1991–2020 and records since 1898 at Frankfort 2 NE, 18 miles northwest, 140 ft higher. NOAA, through RCC-ACIS.
