74° on Nov. 13, 1999, the hottest reading for this week of the year since 1958. Next is 70° in 1990.
Scandia’s center stands about 1,040 ft above sea level. Within three miles the land runs from 670 ft to 1,070 ft, a difference of 400 ft: rolling country.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 8 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 5 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million 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.
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 reaches the Gulf of America by way of the Saint Croix and the Mississippi: about 1,830 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 Scandia; river miles along the main stem, rounded.
Scandia has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 3° in January. A normal year brings about 52 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Scandia normally reaches 44° and falls to 24°. The record high is 70°, in 1990; the record low −2°, in 1959. The most rain on this date, 0.67 in, fell in 2010.
Normals 1991–2020 and records since 1958 at Forest Lake 5 NE, 7 miles northwest, 140 ft lower. NOAA, through RCC-ACIS.
