1° on Nov. 13, 2019, the coldest reading for this week of the year since 1945. Next is 10° in 1986.
Beekmantown’s center stands about 260 ft above sea level. Within three miles the land runs from 100 ft to 520 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Johnson Mountain, about 2,500 ft, 15 miles west-southwest.
Under the town center the state geologic map shows Beekmantown Group (in part) (dolostone, limestone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Early Ordovician, 471 to 487 million years old. About 5 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 4 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Gneiss, metaanorthosite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 459 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Beekmantown reaches the St. Lawrence River by way of Ray Brook, Dead Creek 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.

Beekmantown 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 Beekmantown 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.
