Rescuers have reached a woman injured in a fall on Mount Stuart, about 12 miles southwest of Leavenworth in Chelan County.
A dispatch supervisor in Wenatchee, Dennis Keppner, also says air resources are on the way Thursday morning.
High winds prevented helicopters from reaching the woman Wednesday. But a copter from Whidbey Island Naval Air Station dropped off a deputy and medic overnight about 2,200 feet below the woman's location.
The sheriff's office says the 29-year-old woman was seriously injured when she slid about 800 feet to the 8,900-foot level of the mountain. Her climbing partner called 911 for help.
