A huge 35,000 to 40,000 cubic yard landslide has blocked Highway 26/89 for about 300 feet with material about 40 feet high. The slide is about 2000 feet long, terminating in the Snake River. It is still moving about 1 foot per day. Plans are in place to begin clearing the material, but WYDOT does not want to start until the risk of more material coming down has subsided.

The Chilliwack Times reports that the City of Chilliwack will pay 80% of the assessed home value for up to 42 homes in an Eastern Hillside subdivision that are located on a slow moving landslide. The issue was first noticed in 2001 and several homes have had significant damage, but most are currently undamaged.

Normally the geotechnical engineer for the subdivision would be held accountable. But apparently the slip surface is located 30-m below grade, much deeper than borings for a typical investigation for a subdivision. I wonder if there were any geologists consulted? Click through for a Google map view of the area and you can do your own armchair photogeology quarterbacking! Your heart does go out to the people losing their homes, they had no idea. But it could be worse, they could be in La Jolla and be getting squat.
