Iconic 90-foot Hōlei Sea Arch falls into the sea in Hawaii

The Hōlei Sea Arch, a 90-foot lava rock formation located in Hawaiʻi Volcanoes National Park, collapsed into the Pacific Ocean between September 23 and September 27. The natural structure, which protruded from the park's rocky cliffs, was estimated to be approximately 550 years old.

The collapse marks the end of a prominent geological feature within the national park. While the exact timing of the event remains narrowed to the previous weekend, the loss of the arch represents a significant change to the coastal landscape of the region.
