Doylestown’s center stands about 420 ft above sea level. Within three miles the land runs from 190 ft to 490 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Haycock Mountain, about 980 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Stockton Formation (arkose), from the Triassic, 202 to 252 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 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone. Age: Triassic, 202 to 252 million years old. About 10 mi of the line.
Arkose. Age: Triassic, 202 to 252 million years old. About 6 mi of the line.
Argillite. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Sand, clay. Age: Pleistocene, less than 2.6 million years old. About 0.7 mi of the line.
Basalt. Age: Jurassic, 145 to 202 million years old. About 0.7 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 Doylestown reaches Delaware Bay and the Atlantic Ocean by way of Neshaminy Creek and the Delaware: about 120 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 Doylestown; river miles along the main stem, rounded.
Doylestown has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Doylestown normally reaches 54° and falls to 32°. The record high is 66°, in 2010; the record low 18°, in 1996. The most rain on this date, 0.55 in, fell in 2008.
Normals 1991–2020 and records since 1948 at Sellersville, 10 miles west-northwest, 120 ft lower. NOAA, through RCC-ACIS.
