75° on Nov. 11, 2020, the hottest reading for this week of the year since 1909. Next is 69° in 1948.
Prospect’s center stands about 1,190 ft above sea level. Within three miles the land runs from 760 ft to 1,450 ft, a difference of 690 ft: hilly country. The highest named summit within 15 miles is McCauley Mountain, about 1,940 ft, 15 miles east-northeast.
Under the town center the state geologic map shows Trenton Group (limestone), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 10 mi of the line.
Metasedimentary, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 7 mi of the line.
Black-shale. Age: Middle Ordovician, 459 to 471 million years old. About 6 mi of the line.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.8 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.5 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Prospect reaches New York Harbor and the Atlantic Ocean by way of West Canada Creek, the Mohawk and the Hudson: about 280 river miles.
160 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Prospect; river miles along the main stem, rounded.
Prospect has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 10° in January. About 51 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1909 at Trenton Falls, here, 390 ft lower. NOAA, through RCC-ACIS.
