"I like the established Sierra Nevada method for digging in."
Cross country skiers trying to cross the Sierra Nevada in a minimum number of days need to cut a lot of weight out, and the first step of that is with shelter. I've only slept in the 2-person version, but it also scales up to a 4-person version. If you want to gild the lily, you take one long pole from a real tent (typically aluminum 10') and use it as the primary roof truss. That allows you to keep all of your skis and ski poles free for action.
I wish I still had my old web site from several years ago, because I had a step-by-step instruction with illustrations for this. Oh, well.
