75° on Nov. 16, 1928, the hottest reading for this week of the year since 1880. Next is 75° in 1993.
Otisville’s center stands about 880 ft above sea level. Within three miles the land runs from 500 ft to 1,360 ft, a difference of 860 ft: hilly country. The highest named summit within 15 miles is Kittatinny Mountain, about 1,780 ft, 12 miles south-southwest.
Under the town center the state geologic map shows Austin Glen Formation (graywacke, shale), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 10 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 6 mi of the line.
Sandstone, conglomerate, shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 394 million years old. About 4 mi of the line.
Limestone, dolostone. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 3 mi of the line.
Shale. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Middle Devonian, 384 to 394 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. 4 smaller units along the line are not listed.

A raindrop that lands in Otisville reaches New York Harbor and the Atlantic Ocean by way of Shawangunk Kill and the Hudson: about 160 river miles.
90 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Otisville; river miles along the main stem, rounded.
Otisville has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 16° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Otisville normally reaches 50° and falls to 30°. The record high is 71°, in 1989; the record low 12°, in 1905. The most rain on this date, 1.40 in, fell in 1972.
Normals 1991–2020 and records since 1880 at Port Jervis, 10 miles southwest, 300 ft lower. NOAA, through RCC-ACIS.
