67° on Nov. 13, 1999, the hottest reading for this week of the year since 1911. Next is 66° in 1953.
Barnum’s center stands about 1,130 ft above sea level. Within three miles the land runs from 1,070 ft to 1,230 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Little Falls Formation (schist, slate), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 4 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.
Sandstone, siltstone. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 11 mi of the line.
Volcanic, sedimentary. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
Schist, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.

A raindrop that lands in Barnum reaches the Gulf of America by way of the Moose Horn, the Kettle, the Saint Croix and the Mississippi: about 1,950 river miles.
Lakes on the way: Lake Pepin and Lake Mallalieu 175.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Barnum; river miles along the main stem, rounded.
Barnum has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 2° in January. A normal year brings about 71 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Barnum normally reaches 36° and falls to 23°. The record high is 63°, in 1953; the record low −8°, in 1959. The most rain on this date, 0.40 in, fell in 1951.
Normals 1991–2020 and records since 1911 at Cloquet, 16 miles north-northeast, 140 ft higher. NOAA, through RCC-ACIS.
