72° on Nov. 14, 1999, the hottest reading for this week of the year since 1897. Next is 69° in 1953.
Foreston’s center stands about 1,090 ft above sea level. Within three miles the land runs from 1,040 ft to 1,140 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 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 15 mi of the line.
Granitic. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 4 mi of the line.
Mylonite, gneiss, schist. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Volcanic, sedimentary, hypabyssal. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 0.3 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 Foreston reaches the Gulf of America by way of the West Branch Rum, the Rum and the Mississippi: about 1,960 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Foreston; river miles along the main stem, rounded.
Foreston has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 1° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 31 inches of water.
On November 14 Foreston normally reaches 40° and falls to 22°. The record high is 72°, in 1999; the record low −6°, in 1919. The most rain on this date, 1.11 in, fell in 1909.
Normals 1991–2020 and records since 1897 at Milaca, 3 miles east-northeast. NOAA, through RCC-ACIS.
