Danby’s center stands about 710 ft above sea level. Within three miles the land runs from 650 ft to 3,390 ft, a difference of 2,740 ft: mountain country. The highest named summit within 15 miles is Equinox Mountain, about 3,830 ft, 14 miles south-southwest.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, metasiltstone. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.
Gneiss. Age: Mesoproterozoic, 1.2 to 1.6 billion years old. About 4 mi of the line.
Paragneiss, quartz-feldspar-schist. Age: Mesoproterozoic, 1.2 to 1.4 billion years old. About 3 mi of the line.
Carbonate, marble, sandstone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 3 mi of the line.
Quartzite. Age: Early Cambrian, 521 to 542 million years old. About 2 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1.2 to 1.4 billion 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. 4 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 Danby reaches the St. Lawrence River by way of Otter Creek and the Richelieu: about 240 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
120 miles of the trip are on Otter Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Danby; river miles along the main stem, rounded.
Danby has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 8° in January. A normal year brings about 75 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Danby normally reaches 47° and falls to 26°. The record high is 69°, in 1989; the record low 1°, in 2019. The most rain on this date, 1.20 in, fell in 1937.
Normals 1991–2020 and records since 1916 at Rutland, 19 miles north. NOAA, through RCC-ACIS.
