Comments

Stumbled across a surprising size 1-1.5 in the Heart Strings runout. Not sure exactly when it happened but it looked like it was probably earlier today (Sunday). Variable depth, 25cm at deepest point. Tracks indicated skier triggered (maybe even by two people) but all he tracks that went in came out from the end of the debris pile.

Bed surface was a very firm crust.
