Shandaken’s center stands about 1,080 ft above sea level. Within three miles the land runs from 990 ft to 2,940 ft, a difference of 1,950 ft: steep hill country. The highest named summit within 15 miles is Slide Mountain, about 4,180 ft, 8 miles south.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate, shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Shale, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Shale, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 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.
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 Shandaken reaches New York Harbor and the Atlantic Ocean by way of Panther Kill, Esopus Creek and the Hudson: about 150 river miles.
Lake on the way: Ashokan Reservoir.
100 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shandaken; river miles along the main stem, rounded.
