Two Hikers Die in Falls Days Apart on Washington's Sauk Mountain Trail

Two hikers died in separate falls four days apart on Sauk Mountain Trail in Washington's North Cascades, prompting a multi-agency search-and-rescue effort and renewed warnings about one of the region's most popular but hazardous day hikes.

Peter Kalapaca, 78, of Edmonds, was reported missing on the evening of Sept. 17 after he became separated from family members near the summit of the 4.2-mile round-trip trail, according to the Skagit County Sheriff's Office. Ground crews searched through the night, and a helicopter crew spotted him the next evening in steep, inaccessible terrain off the trail. He was already dead when found, and a technical helicopter recovery was required to bring his body out, the Cascadia Daily News reported.

Two days later, on Sept. 19, a second hiker died on the same trail. Gary Idleburg, 66, of Olympia, fell an estimated 800 to 1,000 feet from a switchback around 3:30 p.m. after other hikers witnessed the fall and called 911, The Spokesman-Review reported. He was pronounced dead at the scene, and his body was recovered by helicopter with help from Washington State Parks personnel and Skagit County Search and Rescue.

The trail and the toll

Sauk Mountain Trail No. 613 climbs about 1,200 feet over 2.1 miles to a 5,300-foot ridge in the Mount Baker-Snoqualmie National Forest, near the town of Concrete. Hikers reach the route from a modest, fee-free trailhead parking area that holds about 25 vehicles, at an elevation already above 4,300 feet. The route is known for sweeping views of Mount Baker, Puget Sound and the San Juan Islands, reached by way of roughly two dozen switchbacks that the U.S. Forest Service's own trail page describes as steep, exposed and prone to erosion where hikers cut corners between switchbacks.

Kalapaca and Idleburg's deaths bring to at least five the number of hikers who have died in falls on the trail since 2017, according to local reporting that also documented fatalities in 2017, 2018 and 2025. Washington Trails Association trip reports for the hike explicitly note that "there have been multiple fatalities due to falls on this trail" and that erosion has "increased the risk of dangerous falls," advice the nonprofit trail-advocacy group publishes alongside its hike description rather than as an official closure notice.

A popular but unforgiving route

Sauk Mountain draws large numbers of day hikers each summer and fall because it delivers alpine views for a relatively modest amount of climbing, making it accessible to hikers of varying experience and fitness levels. Its narrow, sun-exposed switchbacks sit above steep drop-offs with little margin for a misstep, a patch of loose gravel or an early-season snowfield, a combination that outdoor guides and trail reviewers have flagged for years as a source of the mountain's outsized fatality count.

The Forest Service's guidance for the route warns hikers to "stay on the maintained trail and don't cut the switchbacks," both for erosion control and personal safety, and notes that no water is available anywhere along the climb. None of that guidance changed after this month's deaths; the Skagit County Sheriff's Office said the trail, which was briefly affected by the search operations, has since reopened to the public.

The two fatalities also were not the only close call on the mountain that weekend. A third hiker fell roughly 100 feet from a switchback on Sept. 19, the day of Idleburg's death, and was extracted by rescue personnel after sustaining injuries, according to KOMO News and other regional outlets that covered the search. That injury was not fatal, and the hiker's name has not been released.

Who responded

Recovering both bodies required extensive coordination among agencies with no single jurisdiction over the mountain. Skagit County Search and Rescue volunteers, sheriff's deputies, Washington State Parks staff and a helicopter crew from North Cascades National Park all took part in the two operations, which together spanned several days and required technical rope work to reach hikers who had fallen off maintained trail into steep timber and rock. The Forest Service, which manages the land itself as part of the Mount Baker-Snoqualmie National Forest, was not the lead agency on the recovery but has jurisdiction over the trail's maintenance and signage.

The scale of the response reflects a broader pattern in the North Cascades, where popular alpine trails combine heavy visitation with genuinely technical terrain, taxing the volunteer search-and-rescue networks that respond to falls, injuries and missing-hiker calls throughout the summer and fall hiking season.

Reaction

The Skagit County Sheriff's Office thanked the volunteers and agencies involved in recovering Kalapaca's body and extended condolences to his family.

"While nothing can lessen the loss of a loved one, we are grateful for the extraordinary effort made by everyone involved, which allows some measure of closure for the family," the sheriff's office said in a statement reported by the Skagit Valley Herald.

Family members of the two men have not issued public statements, and neither the Forest Service nor the sheriff's office has announced any change to the trail's status, signage or permit system as a result of the deaths.

What happens next

With autumn conditions setting in, land managers and search-and-rescue officials in the North Cascades typically renew seasonal warnings about shortening daylight, sudden weather changes and icy conditions on shaded, high-elevation trails like Sauk Mountain. The sheriff's office and the Forest Service have not announced any joint safety campaign specific to this trail, but both routinely direct hikers to check current conditions before setting out and to carry proper footwear, trekking poles and enough daylight buffer to descend before dark.

Both deaths have been described in official and local reporting as accidental falls consistent with the trail's steep, eroded terrain, with no indication that foul play was involved in either case.
