79° on Nov. 15, 1993, the hottest reading for this week of the year since 1865. Next is 77° in 1973.
Washington Crossing’s center stands about 150 ft above sea level. Within three miles the land runs from 20 ft to 490 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Sourland Mountain, about 640 ft, 14 miles north-northeast.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 36×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone. Age: Late Triassic to Early Jurassic, 175 to 237 million years old. About 6 mi of the line.
Arkose. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Siltstone-mudstone, sandstone-mudstone. Age: Late Triassic, 202 to 237 million years old. About 3 mi of the line.
Gneiss. Age: Precambrian. About 3 mi of the line.
Plutonic. Age: Jurassic, 145 to 202 million years old. About 2 mi of the line.
Argillite. Age: Triassic, 202 to 252 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. 6 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Washington Crossing reaches Delaware Bay and the Atlantic Ocean by way of the Delaware: about 110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Washington Crossing; river miles along the main stem, rounded.
Washington Crossing 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 Washington Crossing 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.
Normals 1991–2020 and records since 1865 from the Trenton Area threaded record (Trenton-Mercer Airport, 3 miles east-southeast). NOAA, through RCC-ACIS.
