Lowell,
It looks like we skied the Nisqually Icefall on May 1, 2008. Our Liberty Ridge descent was May 15, 2012. We did have great conditions, which made it all possible.
I like your cryogenesis idea for a name but I'll have to check with Aaron first.
Thanks for your help! If you need anything else please let me know.
Oliver
