Gilsum Gorge is one of the recorded waterfalls on Ashuelot River in Cheshire County, New Hampshire, in the Northeastern Highlands region. It lies about 7.3 miles north of Keene and roughly 41.3 miles west of Manchester as the crow flies.
No height measurement has been recorded for it yet. The water comes down as a cascade, descending over a series of rock steps rather than in a single drop.
The Northeastern Highlands are the mountains of northern New England and the Adirondacks, with spruce-fir on the summits and northern hardwood forest of maple, beech and birch below, and countless lakes and boulder-strewn brooks. Fast mountain streams drop over granite and gneiss ledges in chains of falls and pools.
