There are multiple crown faces that are wind hammered. It is
difficult to say exactly what happened here; but, it sure looks
like the entire upper bowl (Catcher’s Mit) of the western aspect
avalanched underneath the rock bands. Plus the steep rollover
underneath the Catcher’s Mit appears to have ripped out down the
the ground. That lower avalanche might have been sympathetic to
the upper bowl avalanche or it might have been a seperate event.
We will try to get some more information about this soon.
I didn’t really see any other significant natural avalanche
acitivity at Turnagain Pass from this past storm, but the winds
were so strong that maybe some avalanche debris and crown faces
got buried by wind driven snow?
