6° on Nov. 15, 1959, the coldest reading for this week of the year since 1893. Next is 13° in 1986.
Greenwood’s center stands about 740 ft above sea level. Within three miles the land runs from 640 ft to 820 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Michigan Formation (shale), from the Carboniferous, 324 to 359 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Carboniferous, 324 to 359 million years old. About 17 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 7 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 Greenwood reaches Lake Michigan by way of Cushman Creek, the South Branch White and the White River: about 30 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: White Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenwood; river miles along the main stem, rounded.
Greenwood has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 19° in January. A normal year brings about 69 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Greenwood normally reaches 46° and falls to 33°. The record high is 68°, in 1956; the record low 14°, in 1908. The most rain on this date, 1.40 in, fell in 1908.
Normals 1991–2020 and records since 1893 at Montague 4 NW, 17 miles west. NOAA, through RCC-ACIS.
