Black Cascade is one of the recorded waterfalls on Slide Brook in Grafton County, New Hampshire, in the Northeastern Highlands region. It lies about 11.2 miles east of Woodstock and roughly 63.6 miles west of Portland as the crow flies.
No height measurement has been recorded for it yet. The water comes down as a block waterfall, wider than it is tall, spilling over a broad ledge.
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.
