1° on Nov. 17, 1959, the coldest reading for this week of the year since 1896. Next is 4° in 1933.
Mount Pleasant’s center stands about 720 ft above sea level. Within three miles the land runs from 620 ft to 750 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 million years old.
The section below crosses 2 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.
Dolostone. Age: Silurian, 422 to 445 million years old. About 13 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.

A raindrop that lands in Mount Pleasant reaches Lake Michigan by way of the Pike: about 14 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 Mount Pleasant; river miles along the main stem, rounded.
Mount Pleasant has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 14° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Mount Pleasant normally reaches 47° and falls to 32°. The record high is 72°, in 1971; the record low 7°, in 1986. The most rain on this date, 1.50 in, fell in 1899.
Normals 1991–2020 and records since 1896 at Racine Wwtp, 4 miles east, 130 ft lower. NOAA, through RCC-ACIS.
