0° on Nov. 17, 1959, the coldest reading for this week of the year since 1886. Next is 1° in 1933.
Dyckesville’s center stands about 620 ft above sea level. Within three miles the land runs from 570 ft to 790 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Cherneyville Hill, about 1,020 ft, 15 miles south.
Under the town center the state geologic map shows Maquoketa Formation (shale, dolostone), from the Ordovician, 445 to 487 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 55×. 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 12 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 0.3 mi of the line.

Rain that falls on Dyckesville runs straight into Lake Michigan. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

Dyckesville has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. A normal year brings about 56 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Dyckesville normally reaches 44° and falls to 30°. The record high is 65°, in 1958; the record low 3°, in 1916. The most rain on this date, 0.95 in, fell in 1956.
