18° on Nov. 14, 2019, the coldest reading for this week of the year since 1993. Next is 20° in 1995.
Juliustown’s center stands about 130 ft above sea level. Within three miles the land runs from 50 ft to 210 ft, a difference of 160 ft: gently rolling country.
The section below crosses 7 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 6 mi of the line.
Sand. Age: Middle Miocene, 12 to 14 million years old. About 6 mi of the line.
Clay, sand. Age: Early Miocene, 16 to 23 million years old. About 5 mi of the line.
Sand. Age: Middle Paleocene, 59 to 62 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Juliustown 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 Juliustown; river miles along the main stem, rounded.
Juliustown 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 Juliustown 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, 8 miles west. NOAA, through RCC-ACIS.
