Ausable Chasm is a sandstone gorge and tourist attraction located near the hamlet of Keeseville, New York, United States,[1] due west of Port Kent. The gorge is about two miles (3.2 km) long and is about 150 feet (46 m) deep.[2]

Ausable Chasm is the namesake of the Ausable River, which runs through the gorge and empties into Lake Champlain about one mile (1.6 km) away. The gorge started forming about 10,000 years ago through headward erosion caused by Rainbow Falls, a 91 feet (28 m) waterfall at the gorge's southern extreme.[3] The gorge is a major tourist attraction and landmark in the Adirondacks region of Upstate New York.
