Historic Hanging Boulder Crashes to Ground After 104 Years

A historic hanging boulder, a prominent feature at Polar Caves Park in Rumney, New Hampshire, has fallen after remaining precariously balanced for 104 years. The 100,000-pound rock collapsed on Sunday, October 18, the final day of the park's 2026 season, prompting its immediate closure for the remainder of the year.

The park, located near the White Mountain region, is temporarily shutting its doors to assess the damage and determine next steps. The iconic boulder was a significant draw for the park, attracting thousands of visitors annually. A sign near the site had warned visitors that the boulder was cracked and that 75% of its weight was hanging over the trail.

A hiker captured the aftermath of the collapse on video, showing destroyed railings on the trail leading to the wooden walkway. Fortunately, no visitors were injured in the incident.

Polar Caves Park, which averages approximately 55,000 visitors each year, is known for attractions such as its Nine Granite Boulder Caves, Nature Trails, Animal Exhibit, and a Boulder Maze. The park management plans to use the off-season to evaluate the site's safety and address the damaged cave trail.

"We are incredibly grateful that no one was injured in the incident," a spokesperson for the park stated in a press release. "During the off-season, Polar Caves will assess the site to determine appropriate next steps. We are committed to ensuring that Polar Caves continues to be a fun, memorable, and safe family attraction for generations to come."

The park anticipates reopening for its 2027 season and thanked its guests and the community for their continued support.
