70° on Nov. 15, 1956, the hottest reading for this week of the year since 1886. Next is 70° in 2002.
Ticonderoga’s center stands about 270 ft above sea level. Within three miles the land runs from 90 ft to 1,100 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Hail Mountain, about 2,610 ft, 14 miles northwest.
The section below crosses 17 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.
Quartzite, dolostone. Age: Cambrian, 487 to 497 million years old. About 2 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Shale, phyllite, limestone. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 11 smaller units along the line are not listed.

A raindrop that lands in Ticonderoga reaches the St. Lawrence River by way of the La Chute and the Richelieu: about 180 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 Ticonderoga; river miles along the main stem, rounded.
Ticonderoga has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 9° in January. A normal year brings about 59 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Ticonderoga normally reaches 45° and falls to 29°. The record high is 67°, in 1959; the record low 0°, in 2019. The most rain on this date, 0.93 in, fell in 2021.
Normals 1991–2020 and records since 1886 at Cornwall, 13 miles northeast. NOAA, through RCC-ACIS.
