As a  survivor of two avalanches and other little oddities that other Alaskans have their own parallel "shares" I am about 75% what i use to be. The good ice, bad ice  story should be familiar to your elder friends and I am surprised you need a fuller version. The story was for you to remember and not share the details and results with others. As far as "last laugh" it is one way "first people" dealt with daily tragedies, a list I want subjugate your possible sensitivities  with. One must not upset karma of the cabin or we need to start hiding sharp knives.
Next, "supporters"?, to hold up my socks or other things, thank you for the offer but I am not that kind "share" person. Maybe you are, happy supporting. 
Jay, keep your mucks dry and water out of the gas barrel.
See you down river next spring.
