The first county on our list is King County, home to Seattle but also some amazing landscapes like Snoqualmie Falls. It’s here that steep slopes combined with heavy rainfall create perfect conditions for landslides.

Next up is Snohomish County, which shares many geographical features with its southern neighbor King County but comes with its own unique challenges.

The Oso disaster of 2014 stands as a somber reminder of how quickly things can change; it was one of the deadliest landslides in U.S. history.

With a topography that includes both coastal bluffs and inland hillsides, Snohomish faces frequent soil instability during Washington’s wet seasons.

As you travel along Highway 530 or visit towns such as Arlington or Darrington, there's always in increased chance of danger from traveling that route in Washington State.

Let us not forget Pierce County- where Mount Rainier looms - as another region prone to landslides due to volcanic activity coupled with erosion from glacier-fed rivers. The verdant trails around places like Eatonville offer stunning views but require constant maintenance as shifting soils threaten paths and infrastructure alike.

Another county often discussed when it comes to landslide vulnerabilities is Whatcom County up north near Canada’s border—the landscape here ranges from coastal cliffs overlooking Bellingham Bay down southward toward the farmlands near the Skagit River Valley. Each area brings specific concerns regarding slope stability.
