In an update to our earlier stories, retail giant Wal-Mart has released a statement on Wednesday that they will not build a store at the site of a massive landslide almost a year earlier. They plan to restore the site to a native state complete with trees and other vegetation. The Pennsylvania Department of Environmental Quality is requiring them to submit a new plan for stabilization of the site. Check out the AP article at CentreDaily.

Grant Wilcox, Geology Branch Chief with CALTRANS Office of Geotechnical Design West gave a presentation on the Devil’s Slide repair along PCH Highway 1 at the Southwest Geotechnical Engineer’s Conference on May 12 in Phoenix. I’ve posted about the project here before. When I saw Mr. Wilcox, I knew he looked familiar but I couldn’t figure out why. At the beginning of his presentation he made light of his being on You-Tube…then it clicked! He gave a nice overview of the history of the failures, the geology, and the tunnel project. What follows are a few quick tidbits from his talk based on my notes. (Photo via Caltrans site).
As reported in a previous post, Utah has been considering adopting model legislation for local municipalities to make it more difficult for developers to develop in landslide prone areas. Apparently the Geologic Hazards working group […]
Geology.com pointed out a very nice PDF version of a Power Point presentation by the North Carolina Geologic Survey on their landslide hazard mapping efforts in western North Carolina. The presentation was dated August 1 of last year. The NCGS also has their landslide mapping products available for download, and those so inclined can download the GIS data sets as well.
