Pine Glen’s center stands about 1,530 ft above sea level. Within three miles the land runs from 840 ft to 1,780 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is Bear Knob, about 2,370 ft, 12 miles southeast.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.

A raindrop that lands in Pine Glen reaches Chesapeake Bay and the Atlantic Ocean by way of Redlick Run, the West Branch Susquehanna and the Susquehanna: about 270 river miles.
Lake on the way: Lake Aldred.
140 miles of the trip are on the West Branch Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pine Glen; river miles along the main stem, rounded.
Pine Glen has a cold desert climate. Summer afternoons average 82° in July; winter nights fall to about 18° in January. Barely 0.0 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1982 at Alvin R Bush Dam, 20 miles north-northeast, 600 ft lower. NOAA, through RCC-ACIS.
