68° on Nov. 11, 2022, the hottest reading for this week of the year since 1934. Next is 65° in 2011.
Hermon’s center stands about 500 ft above sea level. Within three miles the land runs from 370 ft to 760 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Huftle Hill, about 1,450 ft, 14 miles southeast.
Under the town center the state geologic map shows Biotite-quartz-plagioclase paragneiss, amphibolite, and related migmatite, from the Mesoproterozoic, 1 to 1.6 billion 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 22×. 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 to 1.6 billion years old. About 6 mi of the line.
Marble. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Marble. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1 to 1.6 billion 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. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Hermon reaches the St. Lawrence River by way of Elm Creek, Harrison Creek, the Grass and the Saint Lawrence: about 65 river miles. The St. Lawrence carries it on to the Atlantic.
55 miles of the trip are on the Grass.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hermon; river miles along the main stem, rounded.
Hermon has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 6° in January. About 42 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1934 at Colton 2 N, 16 miles east-northeast. NOAA, through RCC-ACIS.
