The Hammel plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
−6° on Nov. 17, 1959, the coldest reading for this week of the year since 1946. Next is −5° in 1986.
Hammel’s center stands about 1,340 ft above sea level. Within three miles the land runs from 1,330 ft to 1,480 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Mafic to felsic metavolcanic rocks, from the Paleoproterozoic, 1.6 to 2.5 billion years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 24 mi of the line.

A raindrop that lands in Hammel reaches the Gulf of America by way of Paradise Creek, the Black River, the Dodge Chute and the Mississippi: about 1,840 river miles.

Hammel has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 2° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Hammel normally reaches 40° and falls to 24°. The record high is 66°, in 1999; the record low −4°, in 1986. The most rain on this date, 0.48 in, fell in 1951.
