0° on Nov. 17, 1959, the coldest reading for this week of the year since 1886. Next is 1° in 1933.
Black Creek’s center stands about 800 ft above sea level. Within three miles the land runs from 760 ft to 860 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Mosquito Hill, about 1,010 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
The section below crosses 4 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.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 15 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.

A raindrop that lands in Black Creek reaches Lake Michigan by way of Black Creek, the Shioc, the Wolf River and the Fox River: about 150 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124, Lake Winneconne and Lake Butte des Morts.
55 miles of the trip are on the Wolf River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Black Creek; river miles along the main stem, rounded.
Black Creek has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. A normal year brings about 56 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Black Creek normally reaches 44° and falls to 30°. The record high is 65°, in 1958; the record low 3°, in 1916. The most rain on this date, 0.95 in, fell in 1956.
Normals 1991–2020 and records since 1886 from the Green Bay Area threaded record (Green Bay A S International Airport, 15 miles east, 120 ft lower). NOAA, through RCC-ACIS.
