69° on Nov. 17, 1953, the hottest reading for this week of the year since 1911. Next is 64° in 1913.
Scandia Valley’s center stands about 1,370 ft above sea level. Within three miles the land runs from 1,220 ft to 1,500 ft, a difference of 280 ft: rolling country.
Under the town center the state geologic map shows Mille Lacs and North Range Groups and equivalent sedimentary rocks (siltstone, graywacke, slate), 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 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 9 mi of the line.
Volcanic, sedimentary. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Felsic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.
Schist, paragneiss. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Granitic. Age: Archean to Paleoproterozoic. About 2 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 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.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Scandia Valley reaches the Gulf of America by way of the Crow Wing and the Mississippi: about 1,980 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Scandia Valley; river miles along the main stem, rounded.
Scandia Valley has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −1° in January. About 27 inches of rain fall in a normal year.
On November 14 Scandia Valley normally reaches 38° and falls to 23°. The record high is 65°, in 1953; the record low −5°, in 1911. The most rain on this date, 0.54 in, fell in 1926.
Normals 1991–2020 and records since 1911 at Gull Lake Dam, 13 miles north-northeast, 160 ft lower. NOAA, through RCC-ACIS.
