69° on Nov. 16, 1934, the hottest reading for this week of the year since 1885. Next is 68° in 1953.
Mantrap’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,430 ft to 1,560 ft, a difference of 130 ft: gently rolling country.
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 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Graywacke, mudstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 12 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 6 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.
Granite, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.

Mantrap has a dry-winter warm-summer continental climate. Summer afternoons average 80° in July; winter nights fall to about −3° in January. About 24 inches of rain fall in a normal year.
On November 14 Mantrap normally reaches 37° and falls to 20°. The record high is 64°, in 2025; the record low −12°, in 1940. The most rain on this date, 1.22 in, fell in 1951.
