71° on Nov. 17, 1953, the hottest reading for this week of the year since 1893. Next is 71° in 2001.
Cogswell’s center stands about 1,310 ft above sea level. Within three miles the land runs from 1,290 ft to 1,330 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Carlile Formation (shale), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 2 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.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 13 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.

Cogswell has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 0° in January. About 23 inches of rain fall in a normal year.
On November 14 Cogswell normally reaches 39° and falls to 20°. The record high is 67°, in 2016; the record low −13°, in 1940. The most rain on this date, 0.55 in, fell in 1971.
