74° on Nov. 13, 1999, the hottest reading for this week of the year since 1950. Next is 71° in 1990.
Deer Park’s center stands about 1,080 ft above sea level. Within three miles the land runs from 1,030 ft to 1,180 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Prairie du Chien Group (dolostone), from the Early Ordovician, 471 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 46×. 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: Early Ordovician, 471 to 487 million years old. About 16 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 8 mi of the line.

Deer Park has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 3° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Deer Park normally reaches 42° and falls to 25°. The record high is 71°, in 1990; the record low −1°, in 1959. The most rain on this date, 0.45 in, fell in 1951.
Normals 1991–2020 and records since 1950 at St. Croix Falls, 20 miles northwest, 330 ft lower. NOAA, through RCC-ACIS.
