8° on Nov. 14, 1996, the coldest reading for this week of the year since 1900. Next is 10° in 1911.
Detour’s center stands about 660 ft above sea level. Within three miles the land runs from 570 ft to 770 ft, a difference of 200 ft: gently rolling country.
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 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.
Dolostone. Age: Silurian, 428 to 445 million years old. About 17 mi of the line.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 2 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 Detour reaches Lake Huron by way of Caribou Creek: about 1 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Detour; river miles along the main stem, rounded.
Detour has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 9° in January. A normal year brings about 75 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Detour normally reaches 41° and falls to 30°. The record high is 60°, in 1978; the record low 8°, in 1996. The most rain on this date, 0.95 in, fell in 1978.
Normals 1991–2020 and records since 1900 at Detour Village, 5 miles east. NOAA, through RCC-ACIS.
