Newtown Grant’s center stands about 290 ft above sea level. Within three miles the land runs from 100 ft to 380 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Buckingham Mountain, about 570 ft, 6 miles northwest.
Under the town center the state geologic map shows Lockatong Formation (argillite), from the Triassic, 202 to 252 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 34×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arkose. Age: Triassic, 202 to 252 million years old. About 8 mi of the line.
Mudstone. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Argillite. Age: Triassic, 202 to 252 million years old. About 3 mi of the line.
Sand, clay. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 1 mi of the line.
Dolostone, limestone. Age: Cambrian, 487 to 542 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. 4 smaller units along the line are not listed.

A raindrop that lands in Newtown Grant reaches Delaware Bay and the Atlantic Ocean by way of Newtown Creek, Neshaminy 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 Newtown Grant; river miles along the main stem, rounded.
Newtown Grant has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Newtown Grant normally reaches 55° and falls to 37°. The record high is 72°, in 1993; the record low 16°, in 1986. The most rain on this date, 1.89 in, fell in 1972.
