I keep thinking of trying that... if I can get my hands on a piece of aluminum plate for cheap... the problems that I see is it would be heavy and only work in snow/mud and sand but would still have to be "shoveled" in to harder surfaces, unlike a pull pal which digs in to the harder surfaces too.
Would it be possible to scale up a deadman snow anchor, a fluke, used in climbing to use in sand as a winch anchor. A fluke is pushed into the snow and the cables buried so the top one is level to the snow surface. Tension on the cable causes the fluke to dig down and the wide face of the fluke pushes against the snow holding the load. Here is a picture of a fluke and a sketch of a scaled up version. It would need to be made of stiff metal, maybe 5/16" thick and have maybe a couple of square feet of surface area but this is all supposition on my part, just throwing the idea out there.
