Ice, Dog-bones, and hard climbing

Sorry I haven’t been posting lately. Here are a few interesting links I’ve found lately.

The Black Diamond website has a lot of great videos and interesting technical information. To see some ice climbing from the Ouray Ice Festival, check out Rich Marshall climbing and turn up the volume. There’s also some off-the-record info by Black Diamond’s QA Manager Kolin Powick about device failure in QA with KP. You can read about how many old biners or dog-bones break under 7 kN. He also has web-site with a cool home-movie video of Lauren Lee climbing a 5.13c. Great climbers know how to get some rest on climbs and you see her shaking the pump out.

Also, if you thought you couldn’t screw up by using a daisy chain, you’d better watch this video on the BD site: Daisy Chain Failure Video.
