Hancock’s center stands about 920 ft above sea level. Within three miles the land runs from 890 ft to 1,870 ft, a difference of 980 ft: steep hill country. The highest named summit within 15 miles is Mount Ararat, about 2,640 ft, 14 miles southwest.
Under the town center the state geologic map shows Upper Walton Formation (shale, sandstone, conglomerate), from the Late Devonian, 359 to 384 million years old.
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 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.

A raindrop that lands in Hancock reaches Delaware Bay and the Atlantic Ocean by way of Fish Creek, the East Branch Delaware and the Delaware: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hancock; river miles along the main stem, rounded.
Hancock has a cold desert climate. Summer afternoons average 81° in July; winter nights fall to about 12° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Hancock normally reaches 50° and falls to 27°. The record high is 68°, in 1964; the record low 9°, in 1986. The most rain on this date, 0.97 in, fell in 1961.
