Rappeling Off Sand: The Sandtrap Anchor System

A Revolutionary New Canyon Tool Without a doubt, the most interesting and widely discussed canyoneering innovation of the last year or two has been Steve Woodford‘s “sand anchor”, a simple but brilliant contraption allowing canyoneers to rappel relatively safely off a plentiful canyon resource: sand. Though not nearly as simple or obvious to use as bolts or a tree, Woodford’s design enables trained canyoneers to leave no trace safely and securely in remote, pristine canyons much more easily than previous leading-edge “ghosting” techniques. As this tool, and the understanding of how to use it, spreads through the canyoneering community, I hope to see less new bolting in canyons, and perhaps even less rope scarring as well. The Sand Anchor Concept The fundamental idea behind the anchor design is straightforward: If you can spread a lot of weight over a large enough friction surface, you end up with a safe anchor to rap on. In the past, there have been lots of approaches to this concept, but most of them relied primarily on the weight variable, and not as much on the surface area variable. Thus, we always needed a sharp corner or deep hole to gain enough friction to hold … Continue reading
