70° on Nov. 17, 2016, the hottest reading for this week of the year since 1959. Next is 67° in 1971.
Maple Grove’s center stands about 870 ft above sea level. Within three miles the land runs from 790 ft to 960 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Warner Hill, about 1,160 ft, 4 miles north-northwest.
Under the town center the state geologic map shows Ellsworth Shale, from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 30×. 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: Late Devonian, 359 to 384 million years old. About 14 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 4 mi of the line.

A raindrop that lands in Maple Grove reaches Lake Michigan by way of the Platte: about 25 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: Platte Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maple Grove; river miles along the main stem, rounded.
Maple Grove has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 143 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Maple Grove normally reaches 45° and falls to 31°. The record high is 62°, in 2009; the record low 15°, in 1986. The most rain on this date, 0.88 in, fell in 1969.
Normals 1991–2020 and records since 1959 at Maple City 1 E, 10 miles north. NOAA, through RCC-ACIS.
