72° on Nov. 11, 2020, the hottest reading for this week of the year since 1896. Next is 70° in 1909.
Lake Katrine’s center stands about 200 ft above sea level. Within three miles the land runs from 20 ft to 610 ft, a difference of 590 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Plateau Mountain, about 3,850 ft, 14 miles northwest.
Under the town center the state geologic map shows Onondaga Limestone, from the Early Devonian to Middle Devonian, 388 to 410 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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: Early Devonian to Middle Devonian, 388 to 410 million years old. About 7 mi of the line.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 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.
Sandstone, shale. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Age: Silurian to Early Devonian, 394 to 445 million years old. About 1 mi of the line.
Slate, shale. Age: Ordovician, 445 to 487 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. 3 smaller units along the line are not listed.

A raindrop that lands in Lake Katrine reaches New York Harbor and the Atlantic Ocean by way of Esopus Creek and the Hudson: about 110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Katrine; river miles along the main stem, rounded.
Lake Katrine has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 19° in January. A normal year brings about 59 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 Lake Katrine normally reaches 49° and falls to 35°. The record high is 67°, in 1909; the record low 12°, in 1905. The most rain on this date, 1.95 in, fell in 1972.
Normals 1991–2020 and records since 1896 at Mohonk Lake, 17 miles south-southwest, 900 ft higher. NOAA, through RCC-ACIS.
