80-ton boulder at NH Polar Caves since 1922 collapses, no injuries
On October 18, 2026, an 80-ton granite boulder collapsed at Polar Caves Park in New Hampshire, damaging a walkway but causing no injuries. The incident is attributed to weather-related erosion, prompting park authorities to evaluate the damage. Repairs are planned to ensure visitor safety ahead of the park's reopening in spring 2027.
