Claverack-Red Mills’s center stands about 270 ft above sea level. Within three miles the land runs from 130 ft to 590 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Alander Mountain, about 2,230 ft, 15 miles southeast.
Under the town center the state geologic map shows Nassau Formation (shale), from the Neoproterozoic to Early Cambrian, 521 to 1,000 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Shale. Age: Cambrian to Ordovician, 445 to 542 million years old. About 4 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 2 mi of the line.
Shale, siltstone. Age: Ordovician, 445 to 487 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 Claverack-Red Mills reaches New York Harbor and the Atlantic Ocean by way of Claverack Creek and the Hudson: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Claverack-Red Mills; river miles along the main stem, rounded.
Claverack-Red Mills has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 18° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Claverack-Red Mills normally reaches 52° and falls to 34°. The record high is 71°, in 1989; the record low 14°, in 1986. The most rain on this date, 1.20 in, fell in 1972.
