(CNN) -- The death toll from last month's landslide in Washington state has risen to 41, the Snohomish County Medical Examiner's Office said Monday.
That's up two from Wednesday, when the office updated the news media on recovery efforts.
A rain-saturated hillside along the Stillaguamish River gave way on the outskirts of the rural town of Oso on March 22. Search crews have been digging through deep mud and debris, which is 70 feet thick in some places, to search for the missing.
President Barack Obama is scheduled to visit the area on Tuesday, the one month anniversary of the slide, and meet with search crews.
