I wasn't sure whether to put this in the tech tips section or the accident/near miss section, but now in two separate canyons I have run across someone using burlap bags as a sand anchor. While I appreciate you not bolting the canyon, I can't help but think you should buy and learn to use a sand trap. If you come across one of these, by all means don't use it. Those things are biodegradable and are gradually rotting. I pulled on one of them and have of it came out. That's right, the bag ripped in half. Not to mention it can't possibly take much force to pull the cord off the end of the bag. Seems unnecessarily dangerous to me given other options. I mean, if you're just going to leave something, then bury a deadman. If you want to ghost, get a sandtrap. Another reason to dig up all anchors and never trust webbing coming up out of the sand. I'm curious if anyone knows who is doing this? I know they're buying gear from Atwood because they've left an Atwood VT Prusik on one of these.
