69° on Nov. 17, 1953, the hottest reading for this week of the year since 1911. Next is 64° in 1913.
Maple’s center stands about 1,370 ft above sea level. Within three miles the land runs from 1,280 ft to 1,470 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Ghost Hill, about 1,600 ft, 8 miles south-southwest.
Under the town center the state geologic map shows Mafic metavolcanic rocks (metabasalt, greenstone), from the Neoarchean, 2.5 to 2.8 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 47×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist. Age: Neoarchean, 2.5 to 2.8 billion years old. About 9 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 mi of the line.
Slate, graywacke. Age: Paleoproterozoic, 1.6 to 2 billion years old. About 5 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 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.
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 Maple reaches the Gulf of America by way of Stony Brook, the Gull, the Crow Wing and the Mississippi: about 2,010 river miles.
Lakes on the way: Lake Pepin and Gull Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maple; river miles along the main stem, rounded.
Maple has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −1° in January. About 27 inches of rain fall in a normal year.
On November 14 Maple normally reaches 38° and falls to 23°. The record high is 65°, in 1953; the record low −5°, in 1911. The most rain on this date, 0.54 in, fell in 1926.
Normals 1991–2020 and records since 1911 at Gull Lake Dam, 14 miles south-southeast, 160 ft lower. NOAA, through RCC-ACIS.
