Since my childhood in the 1950s, I've seen snapping turtles at Hawksnest, usually close to Black Pond. Years might go between sightings, but they were definitely there, and some were BIG.

Hawksnest State Park is an orphan, without any budget for maintenance or enforcement. Litter accumulates, parking is out of control, and erosion threatens a pristine pond. People who love the pond are starting a group to assist the State in managing the land and solving its problems. Hawksnest is in Harwich, MA, on Cape Cod.
