(CNN) - A landslide in Washington state killed two people Saturday as it bowled over at least one house, scattering trees, branches and debris over a rural two-lane highway, authorities said.
Snohomish County Sheriff's Office spokeswoman Sherry Ireton reported the fatalities late Saturday afternoon.
Earlier in the day, Lt. Rodney Rochon from the same office said crews were searching for possible victims. Two people were taken to a hospital for minor injuries after being pulled from the mud, he said.
Two others were rescued, according to authorities.
The debris field was so large that authorities weren't sure whether a second home was plowed over, Rochon said.
Photos provided by the Washington State Patrol show floodwaters and sprawling debris covering a rural patch of State Road 530, framed by woodlands and snow-capped mountains. The area is north of Seattle.
Upon arriving at the scene late Saturday morning, firefighters and state troopers heard calls for help, trooper Mark Francis said.
