80° on Nov. 11, 2002, the hottest reading for this week of the year since 1942. Next is 79° in 1955.
Cross Plains’s center stands about 740 ft above sea level. Within three miles the land runs from 610 ft to 810 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Pitt Hill, about 960 ft, 12 miles southeast.
Under the town center the state geologic map shows St. Louis Limestone and Warsaw Limestone, from the Carboniferous, 324 to 359 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 18 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 0.6 mi of the line.

A raindrop that lands in Cross Plains reaches the Gulf of America by way of Honey Run, the South Fork Red, the Red River, the Cumberland, the Ohio and the Mississippi: about 1,230 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cross Plains; river miles along the main stem, rounded.
Cross Plains has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 27° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 Cross Plains normally reaches 59° and falls to 38°. The record high is 77°, in 1999; the record low 15°, in 2019. The most rain on this date, 1.87 in, fell in 1951.
Normals 1991–2020 and records since 1942 at Springfield Experiment Station, 10 miles west-southwest. NOAA, through RCC-ACIS.
