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,

Despite suffering internal bleeding and head trauma, the sole survivor of a rock climbing accident trekked for over 12 hours to find a pay phone to call for help.

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