Cobleskill’s center stands about 930 ft above sea level. Within three miles the land runs from 890 ft to 1,950 ft, a difference of 1,060 ft: steep hill country. The highest named summit within 15 miles is Pine Mountain, about 2,370 ft, 8 miles west.
Under the town center the state geologic map shows Onondaga Limestone (shale), from the Early Devonian to Middle Devonian, 388 to 410 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Shale, siltstone, sandstone. Age: Middle Devonian, 384 to 394 million years old. About 6 mi of the line.
Shale. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 5 mi of the line.
Graywacke, sandstone, siltstone. Age: Late Ordovician, 445 to 459 million years old. About 3 mi of the line.
Sandstone. Age: Early Devonian, 394 to 422 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.

A raindrop that lands in Cobleskill reaches New York Harbor and the Atlantic Ocean by way of Cobleskill Creek, Schoharie Creek, the Mohawk and the Hudson: about 240 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 Cobleskill; river miles along the main stem, rounded.
Cobleskill has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. About 45 inches of rain fall in a normal year.
On November 14 Cobleskill normally reaches 50° and falls to 28°. The record high is 65°, in 2011; the record low 8°, in 2019. The most rain on this date, 0.90 in, fell in 1997.
Normals 1991–2020 and records since 1985 at Lansing Manor, 16 miles south, 180 ft higher. NOAA, through RCC-ACIS.
