The Rapid River plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
74° on Nov. 11, 2022, the hottest reading for this week of the year since 1938. Next is 68° in 2020.
Rapid River’s center stands about 1,080 ft above sea level. Within three miles the land runs from 850 ft to 1,150 ft, a difference of 300 ft: rolling country.
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 22×. 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: Carboniferous, 324 to 359 million years old. About 15 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 8 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 0.8 mi of the line.

A raindrop that lands in Rapid River reaches Lake Michigan by way of the Rapid and the Torch: about 25 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Elk Lake.

Rapid River has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 10° in February. A normal year brings about 132 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Rapid River normally reaches 43° and falls to 28°. The record high is 64°, in 1999; the record low 13°, in 1995. The most rain on this date, 0.58 in, fell in 1957.
