1° on Nov. 13, 2019, the coldest reading for this week of the year since 1945. Next is 10° in 1986.
North Hero’s center stands about 140 ft above sea level. Within three miles the land runs from 90 ft to 170 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Georgia Mountain, about 1,440 ft, 14 miles south-southeast.
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 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Ordovician, 445 to 459 million years old. About 4 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Quartz-feldspar-schist, phyllite, metagraywacke. 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.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 1 mi of the line.
Dolostone. Age: Early Cambrian, 521 to 542 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. 9 smaller units along the line are not listed.

A raindrop that lands in North Hero reaches the St. Lawrence River by way of Lake Champlain and the Richelieu: about 110 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 North Hero; river miles along the main stem, rounded.
North Hero 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 North Hero 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.
