underworld

I'm sure i've read it here before, but i couldn't find it in a search. but.... aiding solo - i've hear/read that a way to do this is by tying in with a clove hitch and adjusting it as you progress. aside from using soloing belay devices, is this the best way to do it? any suggestions for backing it up?

i was up there yesterday and it is no good. swimming in snow thru the upper basin area waist deep. climbed up 90' of the 1st pitch and the snow was knee+ deep powder full depth to the rock - no consolodation or ice. bailed from there...
