I have used things like trekking poles, mountain axes, tree branches and the
likes, very successfully, for anchoring tents, in all kinds of weather.

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.
