Johnson’s center stands about 510 ft above sea level. Within three miles the land runs from 490 ft to 1,570 ft, a difference of 1,080 ft: steep hill country. The highest named summit within 15 miles is The Chin, about 4,350 ft, 9 miles southwest.
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 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Muscovite-schist, gneiss, quartzite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 8 mi of the line.
Muscovite-schist. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 6 mi of the line.
Phyllite. Age: Cambrian, 487 to 542 million years old. About 6 mi of the line.
Muscovite-schist, phyllite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 2 mi of the line.
Schist, greenstone. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 1 mi of the line.
Phyllite, muscovite-schist, quartzite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.9 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.

A raindrop that lands in Johnson reaches the St. Lawrence River by way of Foot Brook, the Lamoille and the Richelieu: about 160 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 Johnson; river miles along the main stem, rounded.
Johnson has a cold desert climate. Summer afternoons average 77° in July; winter nights fall to about 3° in January. Barely 0.0 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1993 at Morrisville Stowe State Airport, 8 miles south-southeast, 230 ft higher. NOAA, through RCC-ACIS.
