The Wolf Den is the most famous feature of Mashamoquet Brook State Park. Legend has it that in 1742, Israel Putnam, who later became a Major General in the Revolutionary War, entered the den and killed Connecticut’s last known wolf, which had been preying on local livestock. This act made Putnam a local hero. The site was added to the National Register of Historic Places in 1985, with a plaque at the entrance recounting the tale. Nearby, visitors can also find Table Rock, a large flat rock, and Indian Chair, a seat-shaped stone ledge.
