Chasm Provincial Park is a provincial park in British Columbia, Canada, located near the town of Clinton. Expanded to 3,067 hectares (7,580 acres) in 1995, the park was originally created in 1940 to preserve and promote a feature known as the Painted Chasm, or simply The Chasm, a gorge created from melting glacial waters eroding a lava plateau over a 10 million year span called the Chilcotin Group.
