East Nassau’s center stands about 1,030 ft above sea level. Within three miles the land runs from 570 ft to 1,510 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is Misery Mountain, about 2,690 ft, 13 miles northeast.
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 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 11 mi of the line.
Graywacke. Age: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Slate, phyllite, schist. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Phyllite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 2 mi of the line.
Phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 1 mi of the line.
Shale, conglomerate, limestone. Age: Cambrian, 487 to 542 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. 2 smaller units along the line are not listed.

A raindrop that lands in East Nassau reaches New York Harbor and the Atlantic Ocean by way of Kinderhook Creek and the Hudson: about 150 river miles.
120 miles of the trip are on the Hudson.

East Nassau has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 14° in January. About 44 inches of rain fall in a normal year.
On November 14 East Nassau normally reaches 47° and falls to 30°. The record high is 63°, in 1959; the record low 13°, in 2019. The most rain on this date, 1.45 in, fell in 1959.
