It has been over 1 year since an excavation for a new Wal-Mart store in Kilbuck Township, PA caused a massive landslide that closed Route 65 for two weeks, and temporarily closed a rail line as well. Strong storms last month apparently caused an increase in the rate of movement of the now instrumented slide. The state DEQ feels the movement is deep-seated, but Wal-Mart disagrees. See our previous coverage or go to the video from the local CBS affiliate or news and photos from the local ABC affiliate.
Earlier this month, there was a massive slope failure on the "Sea to Sky" highway in British Columbia. It is interesting to note that this same area had a large rockslide in 1965, and a photo of this failure is featured on the cover of the classic text, Rock Slope Engineering by Hoek and Bray. The media played up the aspect that this highway is one of the only ways to access the site of the 2010 Winter Olympic games hosted by Vancouver.
The composite image above shows the book cover and the recent rockslide event (Photo credit: Erik Eberhardt of the University of British Columbia by way of Dave’s Landslide Blog). Dave has done a fabulous job collecting photos, facts and links from around the web. In a follow up post, he added some additional photos and discussion. I recently came across an article that described how the highway originally was slated to have a tunnel bypassing the slide, but that the price tag of $200 million (CAN?) for a 1-km stretch killed the project.
