70° on Nov. 14, 1990, the hottest reading for this week of the year since 1948. Next is 69° in 1964.
Dunn’s center stands about 840 ft above sea level. Within three miles the land runs from 720 ft to 1,120 ft, a difference of 400 ft: hilly country. The highest named summit within 15 miles is Tuttle Hill, about 1,220 ft, 12 miles west.
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 34×. 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 22 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Dunn reaches the Gulf of America by way of the Red Cedar, the Chippewa and the Mississippi: about 1,770 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dunn; river miles along the main stem, rounded.
Dunn has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 4° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Dunn normally reaches 43° and falls to 24°. The record high is 70°, in 1990; the record low 4°, in 1996. The most rain on this date, 0.63 in, fell in 2010.
Normals 1991–2020 and records since 1948 at Menomonie, 9 miles north. NOAA, through RCC-ACIS.
