Jobstown’s center stands about 80 ft above sea level. Within three miles the land runs from 40 ft to 210 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Mount Holly, about 230 ft, 6 miles west-southwest.
Under the town center the state geologic map shows Mt. Laurel Formation (sand), from the Late Cretaceous, 72 to 84 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 5 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 4 mi of the line.
Sand. Age: Middle Miocene, 12 to 14 million years old. About 4 mi of the line.
Sand. Age: Middle Paleocene, 59 to 62 million years old. About 3 mi of the line.
Sand. Age: Early Paleocene, 62 to 66 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Jobstown reaches Delaware Bay and the Atlantic Ocean by way of Barkers Brook, Assiscunk Creek and the Delaware: about 100 river miles.
85 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jobstown; river miles along the main stem, rounded.
Jobstown has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 23° in January. A normal year brings about 25 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Jobstown normally reaches 54° and falls to 34°. The record high is 66°, in 2005; the record low 18°, in 2019. The most rain on this date, 0.85 in, fell in 2008.
Normals 1991–2020 and records since 1993 at Philadelphia/Mt. Holly Wfo, 7 miles west-southwest. NOAA, through RCC-ACIS.
