New Garden’s center stands about 420 ft above sea level. Within three miles the land runs from 240 ft to 490 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows "Glenarm Wissahickon" formation (mica-schist), from the Paleozoic, 252 to 542 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 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Schist, gneiss. Age: Paleozoic, 252 to 542 million years old. About 4 mi of the line.
Mica-schist, quartzite. Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Quartzite. Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Sand, clay, silt. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.

A raindrop that lands in New Garden reaches Delaware Bay and the Atlantic Ocean by way of East Branch White Clay Creek, White Clay Creek, the Christina and the Delaware: about 70 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Garden; river miles along the main stem, rounded.
New Garden has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 26° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 New Garden normally reaches 56° and falls to 38°. The record high is 76°, in 1955; the record low 20°, in 1986. The most rain on this date, 2.42 in, fell in 1972.
