3.10 inches of rain fell in two days, the most for this week of the year since records began in 1936. The next wettest, 1.98 inches, fell in 2021.
Galesville’s center stands about 750 ft above sea level. Within three miles the land runs from 670 ft to 1,230 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is Peacock Hill, about 1,260 ft, 10 miles east.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 24 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 0.5 mi of the line.

A raindrop that lands in Galesville reaches the Gulf of America by way of Beaver Creek, the Black River, the Dodge Chute and the Mississippi: about 1,700 river miles.

Galesville has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 9° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Galesville normally reaches 44° and falls to 29°. The record high is 65°, in 1964; the record low 7°, in 1996. The most rain on this date, 0.46 in, fell in 2010.
