My absolute favorite tent anchors are nylon mesh stuff sacks
filled with snow. They hold insanely well. The snow inside
the sack bonds to the snow outside the sack, and you end up
with a web of nylon imbedded in the snow.

Not really any more work than any other kind of deadman; you
don't bury any hardware that you need, and four or five
nylon mesh bags weigh almost nothing.

How about getting those anchors out? Isn't it a problem to dig them out
once they are frozen to the snow? I used traditional (Bibler) snow and sand
anchors on Denali and even those where hard to dig out after a few days.
