Ausable Chasm: Horseshoe and Rainbow Falls Professional Guide
Detailed Trail Description from our Guidebook
"Get ready to explore one of the Adirondacks’ most famous landmarks. Ausable Chasm: The name itself conjures up images of high stone walls, winding trails, narrow passages, 500-million-year-old rock faces, mysterious caves, and gently flowing waters. That’s exactly what Irishman William Gilliland discovered in 1765 when he took a boat up the west shore of Lake Champlain and glided into this almost mystical place on the Ausable River.
Hearing of his discovery, settlers soon followed to make the most of the dependable waterpower and the abundant Atlantic salmon that swam up the river to spawn within the gorge. Mills, lumber industry operations,
iron ore mining and processing, and nail manufacturing moved into the area to make the most of its bountiful natural resources—all powered by the two waterfalls you came here to see: Horseshoe and Rainbow Falls."
