77° on Nov. 12, 1909, the hottest reading for this week of the year since 1898. Next is 76° in 1973.
Pottersville’s center stands about 300 ft above sea level. Within three miles the land runs from 170 ft to 850 ft, a difference of 680 ft: hilly country. The highest named summit within 15 miles is Upper Pohatcong Mountain, about 1,270 ft, 11 miles northwest.
Under the town center the state geologic map shows Passaic Formation Quatzite-clast Conglomerate facies (conglomerate, sandstone), from the Early Jurassic to Late Jurassic, 145 to 202 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 11 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Dolostone. Age: Early Cambrian to Middle Cambrian, 497 to 542 million years old. About 1 mi of the line.
Conglomerate-sandstone. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 1 mi of the line.
Biotite-gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1.0 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 8 smaller units along the line are not listed.

A raindrop that lands in Pottersville reaches New York Harbor and the Atlantic Ocean by way of the Lamington and the Raritan: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pottersville; river miles along the main stem, rounded.
Pottersville has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 21° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Pottersville normally reaches 54° and falls to 34°. The record high is 72°, in 1964; the record low 15°, in 1986. The most rain on this date, 0.94 in, fell in 1940.
