The Arizona Department of Transportation (ADOT) has established a web site to keep the public up to date on the progress in repairing the rupture to US Highway 89 south of Page, AZ. You can access and bookmark the web site here. It really is a great way to keep abreast of the progress as engineers assess what to do to repair the scenic road.
Also, my colleague Chuck Larue forwarded some photographs taken a few days after the rupture. I'm not quite sure how he obtained these photo's so I cannot give any more credit than that. But whomever took them, thank you.
here (fifth and sixth photographs there). This is the block that slipped down from the whitish cliff near the top of this photograph. That surely was one massive slump but just one of many that have occurred on this section of the Echo and Vermilion Cliffs. Slumps do not have to happen catastrophically - they can form by gradual creep. Of course, gradual to the geologist is relative. This massive block could have slipped in one event within a few minutes or it might have taken a few years to decades to get here.

Helen and I are headed to Lake Powell today and of course, we will not be able to drive this section of the highway. We will be taking the Coppermine Road and will report back on its condition. Watch the ADOT web site for updates and check back here for pictures of the Coppermine Road..
