73° on Nov. 16, 1993, the hottest reading for this week of the year since 1942. Next is 72° in 2020.
Knox’s center stands about 1,250 ft above sea level. Within three miles the land runs from 950 ft to 1,500 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is East Hill, about 2,220 ft, 12 miles southwest.
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 10×. 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, sandstone, siltstone. Age: Late Ordovician, 445 to 459 million years old. About 6 mi of the line.
Shale. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 4 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 3 mi of the line.
Sandstone, shale. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Limestone, dolostone. Age: Early Devonian, 394 to 422 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. 2 smaller units along the line are not listed.
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 Knox reaches New York Harbor and the Atlantic Ocean by way of Beaverdam Creek, Fox Creek, Schoharie Creek, the Mohawk and the Hudson: about 250 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 Knox; river miles along the main stem, rounded.
Knox has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. A normal year brings about 46 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Knox normally reaches 48° and falls to 30°. The record high is 66°, in 1964; the record low 8°, in 1971. The most rain on this date, 1.17 in, fell in 1955.
Normals 1991–2020 and records since 1942 at Alcove Dam, 17 miles southeast, 620 ft lower. NOAA, through RCC-ACIS.
