Philip Wszolek, BRACIA! Not so sensitive as totally amused by Josh's imaginative short term memory. I really think I'm going to adopt that nickname. LOL.
Doug, Steve, yes, the tarp/bivy was just a misguided idea with that amount of snowfall. Especially without a ridgeline or center pole. I think with a bombproof bivy, something Epic or eVent, you could still pull it off, but maybe outside the storm season. I also could have dug a real cave with higher walls. But, hey, I knew I was pushing it. I also knew the trip provided two good exit strategies: Josh's Nallo, and a 5 mile trail.
I say go for it if you trust the conditions to be light and you can switch gears as needed. Heck, bring the tent and set it up as backup. At least until you feel experienced and confident in your UL Winter strategies and judgement calls. I'll do it again but not before April.
