It would be quite preferable to make it to the Mount Tuzo col to bivy. However, we did not. Lucky for us however, we did indentify in the dark one of the finer bivy ledges in the Canadian Rockies. Our headlamps flashed what appeared to be a huge overhanging cornice. Upon closer inspection however I noticed a large flat ledge holding this cornice in position. We dropped down one human length off the edge of the ridge onto this airy snowy platform where we were almost completely protected from the wind at just under 11,000’ with 4000’ relief off of the ledge! Four of us were capable of bivying comfortably on this ledge.
