76° on Nov. 16, 1993, the hottest reading for this week of the year since 1931. Next is 73° in 1964.
Salt Point’s center stands about 280 ft above sea level. Within three miles the land runs from 230 ft to 610 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Silver Mountain, about 1,420 ft, 14 miles northeast.
Under the town center the state geologic map shows Normanskill Formation (shale), from the Middle Ordovician, 459 to 471 million years old.
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 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.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 million years old. About 7 mi of the line.
Phyllite, schist, metagraywacke. Age: Middle Ordovician, 459 to 471 million years old. About 5 mi of the line.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Shale. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.
Shale, quartzite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 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. 6 smaller units along the line are not listed.

A raindrop that lands in Salt Point reaches New York Harbor and the Atlantic Ocean by way of Wappinger Creek and the Hudson: about 90 river miles.
70 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Salt Point; river miles along the main stem, rounded.
Salt Point has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. About 42 inches of rain fall in a normal year.
On November 14 Salt Point normally reaches 52° and falls to 32°. The record high is 72°, in 1973; the record low 13°, in 1986. The most rain on this date, 2.01 in, fell in 1972.
Normals 1991–2020 and records since 1931 from the Poughkeepsie Area threaded record (Poughkeepsie/Hudson Valley Regional Airport, 13 miles south-southwest, 130 ft lower). NOAA, through RCC-ACIS.
