80-ton 'Mysterious Hanging Boulder' falls at Polar Caves Park after more than a century
The rock had hung over a walkway in the Rumney park's Boulder Maze since 1922. It fell on the last day of the season, and no one was hurt.
RUMNEY, N.H. | An 80-ton boulder that hung over visitors' heads at Polar Caves Park for more than a century fell Sunday, crushing part of a wooden walkway on the last day of the park's season.
No one was hurt, the park said in a statement posted to social media. "We are incredibly grateful that no one was injured in the incident," Polar Caves wrote, FOX Weather reported.
The rock, known as the "Mysterious Hanging Boulder," had overhung a path in the park's Boulder Maze since the attraction opened in 1922, and visitors walked beneath it as they passed through, ABC22/FOX44 reported. A hand-painted sign at the spot told visitors that about 75% of the boulder's weight hung over the trail, according to Northeast Explorer.
The park said it will assess the site during the offseason to decide what to do next, and that the safety of guests and employees remains its top priority. Officials said they plan to reopen for the 2027 season, WCAX reported. The park normally opens in May.
A video posted by hikers who came upon the scene shortly afterward shows the walkway smashed and blocked, and has spread widely on social media.
Polar Caves, off Route 25 about 5 miles west of Interstate 93 in Plymouth, is a set of granite boulder caves left behind by a continental glacier during the last ice age. The park gets its name from the cold air in the caves, even in midsummer.
The fall came 23 years after the Old Man of the Mountain, New Hampshire's best-known rock formation, collapsed in Franconia Notch in 2003.
