Snohomish County Sheriff's Department said that emergency response crews were coming from Snohomish and Skagit counties.  In addition, a Navy helicopter from Whidbey Island and Snohomish Sheriff's helicopter were responding, the Sheriff's office said.

At least six houses were destroyed, but the Snohomish County Sheriff's Office was still assessing how many other structures may be affected.

The cause of the slide is believed to be ground water saturation from heavy rainfall in the area earlier this month.
