Johnsburg’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,010 ft to 1,860 ft, a difference of 850 ft: hilly country. The highest named summit within 15 miles is Gore Mountain, about 3,600 ft, 6 miles northwest.
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 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.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 8 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 7 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Metaanorthosite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss, metasedimentary. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 0.7 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.
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 Johnsburg reaches New York Harbor and the Atlantic Ocean by way of Baker Brook, North Creek and the Hudson: about 270 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Johnsburg; river miles along the main stem, rounded.
Johnsburg has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 6° in January. A normal year brings about 102 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Johnsburg normally reaches 42° and falls to 26°. The record high is 59°, in 2010; the record low 3°, in 1996. The most rain on this date, 1.20 in, fell in 1949.
Normals 1991–2020 and records since 1899 at Indian Lake 2 SW, 18 miles west-northwest, 370 ft higher. NOAA, through RCC-ACIS.
