The Winhall 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.
70° on Nov. 11, 2020, the hottest reading for this week of the year since 1940. Next is 65° in 2022.
Winhall’s center stands about 2,330 ft above sea level. Within three miles the land runs from 740 ft to 2,660 ft, a difference of 1,920 ft: steep hill country. The highest named summit within 15 miles is Stratton Mountain, about 3,940 ft, 6 miles south-southeast.
Under the town center the state geologic map shows Bondville metadacite and trondhjemite gneiss (paragneiss, metadacite), from the Mesoproterozoic, 1.3 to 1.3 billion years old.
The section below crosses 17 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. 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, 1.2 to 1.6 billion years old. About 5 mi of the line.
Phyllite, metasiltstone. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1.2 to 1.2 billion years old. About 2 mi of the line.
Phyllite, metasiltstone. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Quartzite. Age: Early Cambrian, 521 to 542 million years old. About 2 mi of the line.
Paragneiss, metadacite. Age: Mesoproterozoic, 1.3 to 1.3 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 11 smaller units along the line are not listed.

A raindrop that lands in Winhall reaches Long Island Sound and the Atlantic Ocean by way of the Winhall, the West River and the Connecticut: about 190 river miles.
150 miles of the trip are on the Connecticut.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Winhall; river miles along the main stem, rounded.
Winhall has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 8° in January. About 51 inches of rain fall in a normal year.
