View of Williamson Bowl and Mt Williamson from the summit of Tyndall, showing our path through the bowl. Traversing the bowl didn't take that long and wasn't that hard, just STAY LOW whenever possible. Red line goes by campsites at the first lake, follows gullys to the second lake, wraps partway around the second lake and then heads straight for the black stain. Bottom yellow line runs from black stain to the large chute you ascend. Top yellow line marks approximate location of chimney. Perspective is somewhat distorted by my wide-angle lens.
