New City’s center stands about 200 ft above sea level. Within three miles the land runs from 80 ft to 660 ft, a difference of 580 ft: hilly country. The highest named summit within 15 miles is Blackcap Mountain, about 1,400 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Brunswick Formation (sandstone), from the Late Triassic, 202 to 237 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Late Triassic, 202 to 237 million years old. About 6 mi of the line.
Granite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Gneiss. Age: Precambrian to Mesoproterozoic. About 2 mi of the line.
Amphibolite, hornblende-gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Mudstone, sandstone, arkose. Age: Late Triassic, 202 to 237 million years old. About 2 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 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. 5 smaller units along the line are not listed.

A raindrop that lands in New City reaches New York Harbor and the Atlantic Ocean by way of the Hackensack: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New City; river miles along the main stem, rounded.
New City has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 17° in January. About 50 inches of rain fall in a normal year.
On November 14 New City normally reaches 53° and falls to 32°. The record high is 68°, in 1964; the record low 17°, in 2019. The most rain on this date, 1.18 in, fell in 1955.
Normals 1991–2020 and records since 1950 at Shrub Oak, 15 miles north-northeast, 260 ft higher. NOAA, through RCC-ACIS.
