Keeper potholes are one of the most-feared hazards found in canyons, and for good reason. Not escaping that keeper pothole means your canyon expedition has ground to a halt, and you might be bivied there, for a long time. Soon after discovering keeper potholes, many canyoneers discover the "Pack Toss" as a method for getting past them. Tie a rope to your partner's pack, throw it across the pothole and over the opposite edge, and use the trailing rope to pull yourself out of the pothole. This works fairly well, but for longer and more difficult throws, there is the Pot Shot. Like a little Cordura purse, Pot Shots filled with sand on the spot makes the technique much, MUCH more effective.
