73° on Nov. 13, 1999, the hottest reading for this week of the year since 1872. Next is 71° in 1990.
Mound Prairie’s center stands about 720 ft above sea level. Within three miles the land runs from 650 ft to 1,220 ft, a difference of 570 ft: hilly country. The highest named summit within 15 miles is Fairy Rock, about 1,120 ft, 14 miles southeast.
Under the town center the state geologic map shows Middle and Upper Cambrian (sandstone, siltstone, shale), from the Middle Cambrian to Cambrian, 487 to 521 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 26×. 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, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 13 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 6 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 5 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Mound Prairie reaches the Gulf of America by way of Day Creek, the Root and the Mississippi: about 1,680 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mound Prairie; river miles along the main stem, rounded.
Mound Prairie has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 11° in January. A normal year brings about 46 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Mound Prairie normally reaches 46° and falls to 30°. The record high is 71°, in 1990; the record low 1°, in 1916. The most rain on this date, 1.02 in, fell in 1902.
Normals 1991–2020 and records since 1872 from the La Crosse Area threaded record (La Crosse Regional Airport, 11 miles east-northeast). NOAA, through RCC-ACIS.
