Thar couloir

Went up most of thar north couloir, turned around at a pretty thin rocky step at a choke 50m or so from the top. could go further but not skiable. Majority of the chute goes but would benefit from some more snow, exit is super thin with quite a few rocks and alders poking out. Skinned west up behind yak/nak where it was quite thin, lots of exposed rock, creeks, etc. snow was quite heavy and wet, no signs of instability. Exit was a little thin and harrowing - the theme of the day
