73° on Nov. 11, 2012, the hottest reading for this week of the year since 1961. Next is 71° in 1999.
Walcott’s center stands about 1,180 ft above sea level. Within three miles the land runs from 1,050 ft to 1,250 ft, a difference of 200 ft: gently rolling country.
Under the town center the state geologic map shows Middle and Upper Ordovician (shale, limestone, sandstone), from the Middle Ordovician to Late Ordovician, 445 to 471 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 11 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 9 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 5 mi of the line.

A raindrop that lands in Walcott reaches the Gulf of America by way of the Straight, the Cannon and the Mississippi: about 1,840 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Walcott; river miles along the main stem, rounded.
Walcott has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 5° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Walcott normally reaches 42° and falls to 26°. The record high is 71°, in 1999; the record low 5°, in 2014. The most rain on this date, 0.37 in, fell in 1973.
Normals 1991–2020 and records since 1961 at Owatonna, 10 miles south-southwest. NOAA, through RCC-ACIS.
