Sphinx Cascades is a waterfall in Coos County, New Hampshire, in the Northeastern Highlands region. It lies about 9.3 miles southwest of Gorham and roughly 68.2 miles northwest of Portland as the crow flies.
Its height has not been recorded in the source data. By form it is 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.
