75° on Nov. 11, 2020, the hottest reading for this week of the year since 1963. Next is 74° in 1964.
Crown Point’s center stands about 730 ft above sea level. Within three miles the land runs from 680 ft to 800 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Antrim Shale (black-shale), from the Devonian, 359 to 422 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 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.
Black-shale. Age: Devonian, 359 to 422 million years old. About 13 mi of the line.
Limestone, dolostone. Age: Devonian, 359 to 422 million years old. About 9 mi of the line.
Limestone, dolostone. 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.

A raindrop that lands in Crown Point reaches Lake Michigan by way of the Portage-Burns Waterway: about 35 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 Crown Point; river miles along the main stem, rounded.
Crown Point has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 15° in January. A normal year brings about 30 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Crown Point normally reaches 50° and falls to 31°. The record high is 73°, in 1999; the record low 11°, in 1976. The most rain on this date, 1.62 in, fell in 1972.
Normals 1991–2020 and records since 1963 at Lowell Wwtp, 11 miles south-southwest. NOAA, through RCC-ACIS.
