A massive mudslide approximately 1 mile by 3 miles by 250 feet deep has occured in Western Colorado over the Memorial Day weekend. There are reports that 3 men from the nearby Collbran/Mesa area are missing. According to the Forbes article, the estimates of the size would make it three times the size of the catastrophic Oso landslide in Washington. [Source: Forbes via @CanGeotechJournal.

Devil’s Slide is an infamous landslide along California’s Highway 1 or Pacific Coast Highway near Pacifica, just south of the San Francisco Bay area. Caltrans’ Devil’s Slide Tunnel project is an effort to bypass that slide and make the heavily traveled roadway safe for drivers and to eliminate the maintenance and traffic hassles caused by slope failures blocking the road. We first covered the project back in September of 2007 when the tunnel portion of the project commenced. In that post, you can find a Google Earth KML File showing the location of the tunnels and the new bridges associated with the project. In this post, I’ll provide you with some updated progress information as well as some background on the geotechnical and other aspects of the project. More links and videos are at the end of the post. (Photo by Kim Komenich, San Francisco Chronicle). […]
