Steve: Yes, Iceberg lake. Sorry... didn't study well enough
"The Notch" - I made a mistake on my post above. Once you hit the Notch the final 400 is to your left.
Bottom line: Once you pass the second rappel you go hard right (to were you naturally want to go) and you will end up between two rocks. This is the spot that gives you the option to go right for class 3 or left for class 4/5. We went right.
I saw a photo somewhere of this wedge where you decide to go right or left. This photo was imprinted in my head as "the notch" and gave me reassurance that when I was in that wedge I would get to class 3 vs class 5's.
I can't find the photo now... sorry.
