Lopatcong Overlook’s center stands about 360 ft above sea level. Within three miles the land runs from 170 ft to 1,010 ft, a difference of 840 ft: hilly country. The highest named summit within 15 miles is Scotts Mountain, about 1,290 ft, 7 miles northeast.
Under the town center the state geologic map shows Allentown Dolomite (dolostone), from the Cambrian to Early Ordovician, 471 to 497 million years old.
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 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Lopatcong Overlook reaches Delaware Bay and the Atlantic Ocean by way of Lopatcong Creek and the Delaware: about 150 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lopatcong Overlook; river miles along the main stem, rounded.
Lopatcong Overlook 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 Lopatcong Overlook 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.
