Impressive to watch, huh?  If ya get a chance, stop along Silvertip Creek (shortly after topping out coming up the long draw up from Turnagain Arm, and before the Hope cutoff) and glass that long hogback to the north.  I used to see goats, moose, and bear up there.  Also fun to be there in the spring and watch the avalanches as the hillside thawed.
