10 years after Oso slide, new memorial means 'everything' to survivors

OSO — When Jessica Pszonka stands at the Oso Landslide Memorial, she feels the presence of six family members who perished in 2014.

“Their final resting place was on that slide. That’s where they were taken from us,” she said in an interview last month. “It’s a very healing place. You just get this feeling over you.”

The permanent tribute, located off the renamed Oso Memorial Highway, will be dedicated Friday — as survivors and family gather to mark the 10th year since the tragedy. On the morning of March 22, 2014, the hill above the Steelhead Haven neighborhood collapsed, killing 43 people.

The 2-acre site, built for $4.5 million, takes visitors on a journey honoring the community, first responders, survivors and victims.

What geologists learned from Oso, and what they wish they knew in 2014

OSO — Geologists weren’t shocked when a landslide broke loose near Steelhead Haven in 2014.

“But I think people, including most geologists, were pretty surprised that so much of that mountain went so far so fast,” said University of Washington geomorphologist David Montgomery.

Ten years ago, on the morning of March 22, 2014, the 650-foot-tall hill collapsed above the neighborhood, engulfing the community in 19 million tons of sand, clay and timber. The landslide traveled about a half-mile across the Stillaguamish River valley floor.

“The analogy we often use is kind of like an air hockey table,” said Brian Collins, a U.S. Geological Survey civil engineer. “Instead of the landslide just stopping when it got to the flat areas, it just kept going. It just kept sliding right on out.”
