72° on Nov. 14, 1999, the hottest reading for this week of the year since 1904. Next is 70° in 1953.
Mora’s center stands about 1,010 ft above sea level. Within three miles the land runs from 960 ft to 1,060 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Mylonitic, gneissic, and schistose rocks of plutonic and volcanic protolith (mylonite, gneiss, schist), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. 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 12 mi of the line.
Granitic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Volcanic, sedimentary, hypabyssal. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 3 mi of the line.
Granitic. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 3 mi of the line.
Mylonite, gneiss, schist. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 0.6 mi of the line.
Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Mora reaches the Gulf of America by way of the Snake, the Saint Croix and the Mississippi: about 1,920 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 Mora; river miles along the main stem, rounded.
Mora has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 0° in January. A normal year brings about 52 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Mora normally reaches 40° and falls to 23°. The record high is 72°, in 1999; the record low −5°, in 1919. The most rain on this date, 1.02 in, fell in 1909.
