I recall reading in another thread about a hanger who was looking for a secure ground / soil anchor for a hammock stand. Here is my solution:
I have tried the old reliable three-stakes-in-line method that we all learned in scouting. But due to the angle (30 deg or so) of the diagonal line running to the monopod / bipod / tripod there is a lifting component on the stake nearest the support. I once woke up annd discovered that the two stakes nearest the hammock had been partially pulled from the ground.
I reverted to a load-equalizing system that dates back to my climbing days. I use three big honkin plastic stakes of the type sold at Lowes or at Gander Mountain. I guess that the yellow Reliant stakes could be used, but they are harder to drive. An equalizing sling (minimum 12 feet long after being tied, preferably 20 feet) is strung as in the diagram shows. The sling is looped around the stakes and each of the three loops is clipped through the carabiner. This equalizes the stress on each stake.
I use three stakes, but two or four could be used as well. Depends on your level of security I guess.
No, this is not an ultralight system. I use it for campgrounds and parks where trees are lacking or local enforcement disallows tree-hanging.
BTW, I am using bipods fashioned from 1" EMT conduit. As I said, not for backpacking!
