74° on Nov. 13, 1999, the hottest reading for this week of the year since 1959. Next is 69° in 1990.
Greenbush’s center stands about 1,020 ft above sea level. Within three miles the land runs from 980 ft to 1,050 ft, a difference of 70 ft: gently rolling country.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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 8 mi of the line.
Granitic. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 5 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 4 mi of the line.
Orthogneiss. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 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 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. 2 smaller units 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 Greenbush reaches the Gulf of America by way of Battle Brook, the Saint Francis, the Elk River and the Mississippi: about 1,910 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenbush; river miles along the main stem, rounded.
Greenbush has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 4° 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 Greenbush normally reaches 41° and falls to 24°. The record high is 69°, in 1990; the record low −3°, in 2014. The most rain on this date, 0.52 in, fell in 2010.
Normals 1991–2020 and records since 1959 at Santiago 3 E, 4 miles southwest. NOAA, through RCC-ACIS.
