5° on Nov. 16, 1933, the coldest reading for this week of the year since 1887. Next is 9° in 1959.
Sigel’s center stands about 740 ft above sea level. Within three miles the land runs from 710 ft to 810 ft, a difference of 100 ft: gently rolling country.
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 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Carboniferous, 324 to 359 million years old. About 11 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 10 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 0.4 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 Sigel reaches Lake Huron by way of East Branch Willow Creek and Willow Creek: about 19 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 Sigel; river miles along the main stem, rounded.
Sigel has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. About 33 inches of rain fall in a normal year.
On November 14 Sigel normally reaches 46° and falls to 32°. The record high is 65°, in 1989; the record low 12°, in 1986. The most rain on this date, 1.01 in, fell in 1957.
Normals 1991–2020 and records since 1887 at Bad Axe, 8 miles west. NOAA, through RCC-ACIS.
