On one occasion I was attempting to winch my '40 out of a quicksand pit high up on an alpine ridge. Ithis was complicated by a broken birfield whioch resulted in no power to one of the front tires and that tire just dug deeper as we tried to power/winch forward.
No winch under the tail of that rig (got one waiting for install at the moment though

). and the only rig with me had no winch.
As we attemtped to winch out, I kept dragging the other rig toward me. No trees or rocks up there.
So we dig a couple of holes and dropped the front end of the other rig into the holes. Over the midline of the tires and up against a straight side. The frame was down on the ground and the axle was against the side of the hole too.
It made a fantastic "anchor".
Sadly the only thing it let us do was move my '40 further into the quicksand as the dead front tire just kept plowing in.
But it was an approach that I will keep in mind for any future "stucks" where it might be appropriate and useful.
