The Yorketown plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
79° on Nov. 16, 1993, the hottest reading for this week of the year since 1874. Next is 78° in 1973.
Yorketown’s center stands about 100 ft above sea level. Within three miles the land runs from 60 ft to 200 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Beacon Hill, about 430 ft, 8 miles northeast.
Under the town center the state geologic map shows Englishtown Formation (sand, clay), from the Late Cretaceous, 72 to 84 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 60×. 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, clay. Age: Late Cretaceous, 72 to 84 million years old. About 13 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 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.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 1.0 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 Yorketown reaches New York Harbor and the Atlantic Ocean by way of Milford Brook, McGellairds Brook, Matchaponix Brook, the South River and the Raritan: about 30 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Yorketown; river miles along the main stem, rounded.
Yorketown has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 49 inches of rain fall in a normal year.
On November 14 Yorketown normally reaches 57° and falls to 36°. The record high is 76°, in 1993; the record low 20°, in 2019. The most rain on this date, 0.85 in, fell in 2008.
