73° on Nov. 16, 1989, the hottest reading for this week of the year since 1883. Next is 71° in 2002.
St. George’s center stands about 550 ft above sea level. Within three miles the land runs from 320 ft to 1,090 ft, a difference of 770 ft: hilly country. The highest named summit within 15 miles is Camels Hump, about 4,020 ft, 13 miles east-southeast.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, quartzite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.
Muscovite-schist, phyllite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Marble. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Carbonate, marble, sandstone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 1 mi of the line.
Muscovite-schist, gneiss, quartzite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 1 mi of the line.
Quartz-feldspar-schist, phyllite, metagraywacke. Age: Neoproterozoic to Cambrian, 487 to 1,000 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. 6 smaller units along the line are not listed.

A raindrop that lands in St. George reaches the St. Lawrence River by way of the Winooski and the Richelieu: about 140 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. George; river miles along the main stem, rounded.
St. George has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 13° in January. A normal year brings about 88 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 St. George normally reaches 47° and falls to 33°. The record high is 67°, in 1959; the record low 10°, in 1996. The most rain on this date, 1.14 in, fell in 2009.
Normals 1991–2020 and records since 1883 from the Burlington Area threaded record (Burlington International Airport, 6 miles north, 220 ft lower). NOAA, through RCC-ACIS.
