This is not the first time I’ve posted links to blog posts from the Ontario-geofish blog by Harold A. Some times I blatantly rip him off, but hopefully he doesn’t mind since I try to credit him whenever I post about an article he found. I guess he has more time for surfing since he’s retired! 🙂 Here are a couple of his recent posts that I found interesting. (Image by NASA)
The Colorado Geologic Survey has a very comprehensive overview of the geologic hazard of rockfall in all its many forms in their latest issue of RockTalk newsletter. The entire 24-page newsletter is devoted to various aspects of the problem, mitigation options and case studies all with excellent photos. I highly recommend that you check it out.

A large landslide has closed SR 14 east of Cedar City, Utah. UDOT expects that the road will be closed for up to 2 weeks for cleanup and to ensure that the slope is safe. Boulders up to an estimated 20 tons are now blocking the road and will likely need to be blasted down to a smaller size. A UDOT spokesman interviewed on the video shown after the break estimate the size of the slide at 700 to 800-ft long and 10 to 12-ft thick.
