The Hōlei Sea Arch, a natural lava formation on Hawaii's Big Island near Hawaii Volcanoes National Park, has collapsed into the ocean. The collapse removes one of the area's well-known coastal landmarks, formed over years by wave erosion of lava cliffs. Observers are noting the ongoing reshaping of Hawaii's volcanic coastline and the natural forces behind such formations.

Backpacker Magazine highlights a long-distance hiking trail on a French island in the Indian Ocean, calling it France's toughest thru-hike.

The Hōlei Sea Arch, a well-known natural rock formation on Hawaii's Big Island near Hawaii Volcanoes National Park, has collapsed into the Pacific Ocean. The arch, long a popular sight for visitors along the Chain of Craters Road coastline, was gradually shaped by volcanic rock and ocean erosion. Officials and observers are noting the loss of a distinctive coastal landmark.

Giant flightless birds may have reached a remote volcanic island by drifting across the sea on floating rafts of vegetation, according to new research reported by science outlets. The finding challenges long-held assumptions that such birds, incapable of flight, could only have spread over land connections, and suggests ocean dispersal may explain how similar species colonised isolated islands.
