Interpreting the Evidence
Boating in Ausable Chasm, c. 1900
Suggested Teaching Instructions
A group of men and women prepare to launch a boat from Table Rock in Ausable Chasm, c. 1900.
Ausable Chasm, located in Keesville, New York, is a gorge made out of sandstone. The Ausable River runs through it and ends at Lake Champlain. Ausable Chasm is sometimes called the "Little Grand Canyon of the East." No one is sure when the chasm was discovered, but the 1765 journal of an Irish man, William Gilliland, describes it:
“It is a most admirable sight, appearing on each side like a regular built wall, somewhat ruined, and one would think that this prodigious cliff was occasioned by an earthquake, their height on each side is from 40 to 100 feet in the different places; we saw about a half a mile of it, and by its appearance where we stopped it may continue very many miles further.”
By the 1800s, Ausable River was used for powering paper mills and grist mills. Additionally, it was used to move logs that had been cut for lumber by floating them down the river to Lake Champlain, where they could be placed on ships and taken to any location.
