Heavy rain and thunderstorms over the weekend took a double whammy at primary driving routes in the North Cascades, including a Sunday afternoon washout of the Cascade River Road, a key access to North Cascades National Park backcountry.
The washout, at Boston Creek, 1.5 miles below the popular Cascade Pass Trailhead, stranded 65 people in their cars overnight.
The same series of storms caused multiple landslides closing Highway 20 west of Rainy Pass (see story here).
National Park Service employees were at the Cascade River Road site Monday assisting stranded visitors, and a temporary one-lane road may be opened by day’s end to allow the 25 to 35 trapped vehicles to drive out, according to an email from Ken Hires, Stehekin District Interpreter for the park. Friends and family members of the stranded hikers have been informed of their situation, he said.
The road follows the Cascade River eastward, branching off from Highway 20 near Marblemount, Skagit County, and winds 23 miles to the trailhead. Cascade Pass is one of the most popular destination hikes in North Cascades National Park. Cascade River Road is closed to the public at the park boundary at Milepost 18 until further notice.
