Deputies say a woman called 911 late Sunday night to report that her 52-year-old husband, their son and one of his friends hadn't returned home as scheduled.
Search and rescue personnel and volunteers, along with a sheriff's office helicopter, headed out at about 5:30 a.m. Monday. Their vehicle was found at the Trout Creek Trail about two hours later.
Monday afternoon, the hikers were found in the Trout Creek area, deputies said. One hiker has already been hoisted out by helicopters. Two hikers and their dog are expected to be flown out by the helicopter as soon as rescuers can get the proper equipment to secure their dog.
Officials said all three hikers were fine, just lost.
In a separate incident Monday morning, Snohomish County rescue crews came to the aid to a woman in her 50s who injured her knee in a fall along the Pacific Crest Trail. The woman activated a personal locator beacon monitored by a private company because she knew she wouldn't be able to hike out, and a sheriff's office helicopter picked her up near Mica Lake.
