Glendon’s center stands about 230 ft above sea level. Within three miles the land runs from 150 ft to 860 ft, a difference of 710 ft: hilly country. The highest named summit within 15 miles is Scotts Mountain, about 1,290 ft, 12 miles northeast.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Cambrian, 487 to 542 million years old. About 6 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Dolostone. Age: Cambrian to Early Ordovician, 471 to 497 million years old. About 3 mi of the line.
Gneiss. Age: Precambrian. About 2 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units 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 Glendon reaches Delaware Bay and the Atlantic Ocean by way of the Lehigh and the Delaware: about 160 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Glendon; river miles along the main stem, rounded.
Glendon has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 21° in January. About 51 inches of rain fall in a normal year.
On November 14 Glendon normally reaches 54° and falls to 33°. The record high is 66°, in 2010; the record low 19°, in 2019. The most rain on this date, 0.43 in, fell in 2008.
Normals 1991–2020 and records since 1940 at Phillipsburg-Easton Bridge, 3 miles northeast. NOAA, through RCC-ACIS.
