69° on Nov. 11, 2020, the hottest reading for this week of the year since 1990. Next is 68° in 2002.
Morgan’s center stands about 1,940 ft above sea level. Within three miles the land runs from 1,280 ft to 2,270 ft, a difference of 990 ft: steep hill country. The highest named summit within 15 miles is Gore Mountain, about 3,330 ft, 7 miles east-northeast.
Under the town center the state geologic map shows Echo Pond pluton - granodiorite and granite (granodiorite, granite), from the Devonian, 359 to 422 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite, pegmatite. Age: Devonian, 359 to 422 million years old. About 7 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 6 mi of the line.
Granodiorite. Age: Middle Devonian to Early Mississippian, 353 to 387 million years old. About 4 mi of the line.
Granodiorite, granite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 3 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Morgan reaches the St. Lawrence River by way of the Clyde, the Magog and the Saint-François: about 190 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Memphremagog.
120 miles of the trip are on the Saint-François.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Morgan; river miles along the main stem, rounded.
Morgan has a warm-summer humid continental climate. Summer afternoons average 76° in July; winter nights fall to about 3° in January. A normal year brings about 115 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Morgan normally reaches 42° and falls to 27°. The record high is 60°, in 2010; the record low −3°, in 2019. The most rain on this date, 0.31 in, fell in 2021.
Normals 1991–2020 and records since 1990 at Island Pond, 6 miles south-southeast, 740 ft lower. NOAA, through RCC-ACIS.
