Ausable Chasm

Ausable Chasm is as breathtaking now as it was 400 years ago when Samuel De Champlain first explored the Champlain Valley. People of all ages enjoy the natural splendor of this Adirondack wonder which began its formation during the Cambrian age - 500 million years ago! This is when the rushing water of the powerful Ausable River began cutting its way deeper into a fault in the Potsdam sandstone strata. Today a tour of Ausable Chasm is an education on Adirondack natural history and a recreational vacation rolled into one!
