|Scarp at head of landslide|
As of May 28, an 82 acre patch had slid 20 feet down the mountain, and was sliding a few inches a day. Spring melt from a heavy snowpack and heavy spring rains (9-12 inches in early May) had saturated the ground, triggering the slide. The ground on the mountain is composed of sand and glacial till. It had been hoped that the spring blossoming of the trees would draw enough water out of the ground to slow or stop the slide. Unfortunately, that has not been the case. The movement stopped for a few days, but then picked up at an increasing rate and is now moving up to a foot a day. Residents are trying to move their homes, but insurance does not cover landslides in this area, the cost is ~$100,000, and time is running out. One couple reports 15 feet of open air between their bedroom and the ground below (see article link in figure above).
As of today, the TimesUnion reports that the scarp at the head of the landslide is eight tenths of a mile long and that the slide continues about a half-mile down the mountain. The vertical drop between the scarp and the toe is 300 feet. Kozlowski says that LIDAR (Light Detection And Ranging) mapping might have revealed landslide risks under the thick forest canopy, but has never been done.
