Tichigan’s center stands about 800 ft above sea level. Within three miles the land runs from 760 ft to 890 ft, a difference of 130 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.
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 59×. 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 17 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Tichigan reaches the Gulf of America by way of the Fox River, the Illinois and the Mississippi: about 1,580 river miles.
Lakes on the way: Peoria Lake and Fox Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tichigan; river miles along the main stem, rounded.
Tichigan has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 12° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Tichigan normally reaches 46° and falls to 29°. The record high is 70°, in 1971; the record low 6°, in 1986. The most rain on this date, 1.09 in, fell in 1899.
Normals 1991–2020 and records since 1893 at Waukesha Wwtp, 12 miles north-northwest. NOAA, through RCC-ACIS.
