72° on Nov. 11, 2022, the hottest reading for this week of the year since 1924. Next is 67° in 2001.
Collins’s center stands about 810 ft above sea level. Within three miles the land runs from 790 ft to 900 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 million years old.
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, 422 to 445 million years old. About 24 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 Collins reaches Lake Michigan by way of Mud Creek and the Manitowoc: about 30 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 Collins; river miles along the main stem, rounded.
Collins has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 32 inches of water.
Normals 1991–2020 and records since 1924 at Brillion, 7 miles northwest. NOAA, through RCC-ACIS.
