The St. Albans 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.
1° on Nov. 13, 2019, the coldest reading for this week of the year since 1945. Next is 10° in 1986.
St. Albans’s center stands about 400 ft above sea level. Within three miles the land runs from 90 ft to 1,200 ft, a difference of 1,110 ft: steep hill country. The highest named summit within 15 miles is Gilson Mountain, about 1,960 ft, 10 miles southeast.
Under the town center the state geologic map shows Skeels Corners Slate, from the Cambrian to Early Ordovician, 471 to 542 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Quartz-feldspar-schist, phyllite, metagraywacke. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 7 mi of the line.
Shale. Age: Late Ordovician, 445 to 459 million years old. About 3 mi of the line.
Phyllite, quartzite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Slate. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 2 mi of the line.
Slate, sedimentary-breccia, dolostone. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Limestone. Age: Late Ordovician, 445 to 459 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in St. Albans reaches the St. Lawrence River by way of Stevens Brook and the Richelieu: about 120 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
80 miles of the trip are on the Richelieu.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of St. Albans; river miles along the main stem, rounded.
St. Albans has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 10° in January. About 31 inches of rain fall in a normal year.
On November 14 St. Albans normally reaches 46° and falls to 29°. The record high is 64°, in 1959; the record low 11°, in 2019. The most rain on this date, 0.88 in, fell in 2009.
