The problem with that area that has the mudslides is that the hills next to the track are mostly made of glaciated sand and the base of the hills are made up of a thick clay layer. When there is alot of rain the water goes down through the sand and hits the clay layer and when the water at the clay layer builds up to a point the sand layers just above the clay slide over the track and into the sound. A few years ago when there was a lot of snow in the northern Rockies and snow slide happen BNSF did use the 48-hour rule around Whitefish.
