size 1 in avalanche couloir

good size 1 drought me 40m down in avalanche Couloir. 15cm thick with a big flat slick crust underneath. didn't burry me but enough to give me a big scared!! I have been able to stop at one point where the couloir get a bit less steep. from what I saw of the layer underneath this couloir will probably stay very touchy after each snow fall all winter. No harm, no pain in final but even with a moderate risk things can turn bad very quickly!! stay safe out there!!!
