The Tyringham 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.
74° on Nov. 11, 2020, the hottest reading for this week of the year since 1996. Next is 68° in 2002.
Tyringham’s center stands about 930 ft above sea level. Within three miles the land runs from 850 ft to 1,970 ft, a difference of 1,120 ft: steep hill country. The highest named summit within 15 miles is Haskell Hill, about 2,240 ft, 14 miles northeast.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Gneiss, amphibolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Mica-schist. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Marble. Age: Early Cambrian, 521 to 542 million years old. About 1 mi of the line.
Marble. Age: Early Cambrian, 521 to 542 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 9 smaller units along the line are not listed.

A raindrop that lands in Tyringham reaches Long Island Sound and the Atlantic Ocean by way of Hop Brook and the Housatonic: about 130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tyringham; river miles along the main stem, rounded.
Tyringham has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 13° in January. About 49 inches of rain fall in a normal year.
On November 14 Tyringham normally reaches 47° and falls to 28°. The record high is 68°, in 2010; the record low 8°, in 1996. The most rain on this date, 0.87 in, fell in 1997.
