Whitehall’s center stands about 140 ft above sea level. Within three miles the land runs from 90 ft to 1,140 ft, a difference of 1,050 ft: steep hill country. The highest named summit within 15 miles is Black Mountain, about 2,640 ft, 7 miles west-northwest.
The section below crosses 16 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.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Graywacke, siltstone. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Slate, phyllite. Age: Early Cambrian to Middle Cambrian, 497 to 542 million years old. About 1 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 1 mi of the line.
Gneiss, anorthosite. 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. 10 smaller units along the line are not listed.

A raindrop that lands in Whitehall reaches the St. Lawrence River by way of the Mettawee and the Richelieu: about 210 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
90 miles of the trip are on the Mettawee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Whitehall; river miles along the main stem, rounded.
Whitehall has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. About 38 inches of rain fall in a normal year.
On November 14 Whitehall normally reaches 47° and falls to 28°. The record high is 67°, in 1973; the record low 5°, in 1905. The most rain on this date, 1.45 in, fell in 2009.
Normals 1991–2020 and records since 1893 from the Glens Falls Area threaded record (Glens Falls/Floyd Bennett Memorial Airport, 18 miles southwest, 180 ft higher). NOAA, through RCC-ACIS.
