Frank, your last video shows you were at the point where you climb up, I think. SO close!
Here is my
Mountaineers Route set, starting with a picture with the first seep in view. There are over a dozen pictures showing where I climbed. Actually the set is from two separate years. The first one, we climbed the seep. The second, we climbed the rocky "ramp-like" area that goes up and to the right, and tops out right at Iceberg Lk.
Read the captions on the pictures. I think that will help.
