Danville’s center stands about 1,420 ft above sea level. Within three miles the land runs from 960 ft to 2,030 ft, a difference of 1,070 ft: steep hill country. The highest named summit within 15 miles is Wheelock Mountain, about 2,780 ft, 10 miles north.
Under the town center the state geologic map shows Waits River Formation - carbonaceous phyllite and limestone member (phyllite, limestone), from the Silurian to Early Devonian, 394 to 425 million years old.
The section below crosses 4 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.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 11 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 7 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 5 mi of the line.
Metasandstone, metasiltstone, phyllite. Age: Middle Cambrian to Early Ordovician, 485 to 500 million years old. About 1 mi of the line.

A raindrop that lands in Danville reaches Long Island Sound and the Atlantic Ocean by way of Brown Brook, Joes Brook, the Passumpsic and the Connecticut: about 290 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Danville; river miles along the main stem, rounded.
Danville has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 9° in January. A normal year brings about 87 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Danville normally reaches 46° and falls to 29°. The record high is 64°, in 1989; the record low 3°, in 1905. The most rain on this date, 1.64 in, fell in 1937.
Normals 1991–2020 and records since 1894 at Saint Johnsbury, 6 miles east, 720 ft lower. NOAA, through RCC-ACIS.
