75° on Nov. 11, 2020, the hottest reading for this week of the year since 1909. Next is 69° in 1948.
Oriskany’s center stands about 440 ft above sea level. Within three miles the land runs from 410 ft to 760 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Tassel Hill, about 1,960 ft, 15 miles south.
Under the town center the state geologic map shows Utica Shale (black-shale), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 5 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.
Black-shale. Age: Middle Ordovician, 459 to 471 million years old. About 10 mi of the line.
Siltstone, shale. Age: Late Ordovician, 445 to 459 million years old. About 5 mi of the line.
Shale. Age: Silurian, 422 to 445 million years old. About 5 mi of the line.
Shale. Age: Silurian, 434 to 445 million years old. About 2 mi of the line.
Siltstone, shale. Age: Late Ordovician, 445 to 459 million years old. About 2 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 Oriskany reaches New York Harbor and the Atlantic Ocean by way of the Mohawk and the Hudson: about 270 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 Oriskany; river miles along the main stem, rounded.
Oriskany 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, 12 miles northeast, 360 ft higher. NOAA, through RCC-ACIS.
