How about getting those anchors out? Isn't it a problem to dig them out
once they are frozen to the snow?

Yes. That is the main problem. I have had to chip them out
with the ice axe adze on occasion, but I can usually get
them out with just a shovel. However, I would rather have my
tent anchored to something that is difficult to remove than
to have it anchored to something that melts out after a few
hours of midday sun.
