Lebanon’s center stands about 1,550 ft above sea level. Within three miles the land runs from 1,110 ft to 1,670 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is North Knob, about 2,690 ft, 15 miles west.
Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 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, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 23 mi of the line.
Sandstone, shale. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in Lebanon reaches Delaware Bay and the Atlantic Ocean by way of East Branch Dyberry Creek, Dyberry Creek, the Lackawaxen and the Delaware: about 280 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lebanon; river miles along the main stem, rounded.
Lebanon has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 12° in January. A normal year brings about 69 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Lebanon normally reaches 45° and falls to 27°. The record high is 64°, in 1964; the record low 5°, in 1986. The most rain on this date, 1.30 in, fell in 1972.
Normals 1991–2020 and records since 1924 at Pleasant Mount 1 W, 9 miles west-northwest, 250 ft higher. NOAA, through RCC-ACIS.
