Hiking and Scrambling at Purgatory Chasm

Purgatory Chasm State Reservation, managed by the Massachusetts Department of conservation and Recreation, is notable for its .25-mile long, 70-foot deep chasm of granite bedrock featuring abrupt precipices and boulder caves in which ice lingers into the early summer. According to the most recent research, the Chasm was created when glacial melt water from a burst ice dam ripped out blocks of bedrock at the end of the last Ice Age (14,000 years ago).

We'll explore many areas of the Chasm! Bring your own water, food, bug dope, and other hiking necessities. Meet at 12:30 for the hike, or 11:30 if you want to picnic first.
