Three people died and a fourth was injured while rock climbing in the North Cascades in Washington state, authorities said. Authorities in Okanogan County said the climbers were believed to be rappelling a steep gulley near North Early Winters Spire when their anchor failed,

Authorities suspect the group's anchor point failed, sending four men plummeting. On Wednesday, the survivor was in stable but critical condition with head trauma and internal injuries.

Three rock climbers fell to their deaths Sunday in Washington state, authorities said. Investigators believe their equipment failed as they were descending a ravine.
