Preston-Potter Hollow’s center stands about 1,310 ft above sea level. Within three miles the land runs from 780 ft to 2,050 ft, a difference of 1,270 ft: steep hill country. The highest named summit within 15 miles is Black Dome, about 3,980 ft, 12 miles south-southeast.
The section below crosses 7 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, shale. Age: Middle Devonian, 384 to 388 million years old. About 8 mi of the line.
Shale, siltstone, sandstone. Age: Middle Devonian, 384 to 394 million years old. About 6 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 394 million years old. About 6 mi of the line.

A raindrop that lands in Preston-Potter Hollow reaches New York Harbor and the Atlantic Ocean by way of Catskill Creek and the Hudson: about 150 river miles.
110 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Preston-Potter Hollow; river miles along the main stem, rounded.
