72° on Nov. 11, 1964, the hottest reading for this week of the year since 1893. Next is 71° in 2001.
Henrietta’s center stands about 930 ft above sea level. Within three miles the land runs from 790 ft to 1,260 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Pikes Peak, about 1,320 ft, 14 miles north.
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 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.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 13 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 11 mi of the line.

A raindrop that lands in Henrietta reaches the Gulf of America by way of the Pine River, the Wisconsin and the Mississippi: about 1,700 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Henrietta; river miles along the main stem, rounded.
Henrietta has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 8° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Henrietta normally reaches 46° and falls to 28°. The record high is 70°, in 1971; the record low −4°, in 1916. The most rain on this date, 0.40 in, fell in 2010.
Normals 1991–2020 and records since 1893 at Reedsburg Wwtp, 19 miles east. NOAA, through RCC-ACIS.
