The rock at left travelled nearly a mile down the slope and picked up some significant velocity before impacting a house, hitting the back wall and damaging the ceiling before dropping through the floor into the garage and damaging the garage door. In an often-overlook advantage of the current financial crisis, the house was currently in foreclosure and therefore not occupied at the time of the damage. Read on for links, more info and a map of the location so you can view the terrain. (Photo by Provo Fire Department by way of Utah Geologic Survey)
The Devil’s Slide Tunnel project is on schedule and on budget according to a news story at ABC7News.com from earlier in June. The video (shown after the break) has a few nice shots showing rock bolting, soil nailing at the portals, and the geologic mapping and laser scanning that happens at the tunnel face.
I also came across a very neat article about how the Ocean Shore Railroad Company was the first to try to cut into the slope along what is now PCH 1 at the Devil’s Slide back in the early 1900s. They were trying to connect the then rural farming community of Half-Moon Bay with San Francisco. The railroad fought the reoccurring landslide and serious rockfalls. Ocean Shore Railroad went bankrupt in 1922 and pulled up its rails, making room for the current highway. (Photo at left from halfmoonbaymemories.com)
