Grant Wilcox, Senior Engineering Geologist on the Slide repair project, explains how how the Devil’s Slide geology works, why it is so unstable, how it was repaired in 1995, why Caltrans has temporarily suspended activity on the Slide, and why Caltrans can’t simply build a bridge over the damaged portion of the Slide.

This is the best explanation that we have seen of the geology and dynamics of the slide. If you want to understand what’s happening, you must watch this video.

Wilcox spoke Wednesday night at the Midcoast Community Council. The full meeting will be cablecast tonight on MCTV, but this is the part you must not miss.

Having problems with our videos? Coastsider’s videos should work correctly with Mac and Windows. But they require the most recent version of Quicktime. You can download Quicktime free from Apple.

Thank you, thank you, thank you for posting this video and for providing the best coverage of this anywhere. You are an invaluable resource for all of us that live on and love the coastside.

Darin and Barry: Thanks for providing such a tremendous public service. After watching that video, I have to say that I think the criticism of CalTrans on the slow pace of repair work thus far might be a bit overdone. They are facing an incredibly complex (an expensive) task to rebuild a road in place where nature does want a road to be rebuilt. In the contest, I guessed it would take 96 days to re-open the road. Now I think I should have guessed higher.
