We started on the northwest end of the ridge (the right side - looking from the Whistlers' summit) because this was expected to be the most difficult part of this easy scramble. This was a nice way for increasing the level of adrenaline in the body a little bit ;-)
Almost at the end of the harder part is a window in the ridge.
After passing this harder part, the way to the left-hand summit of the ridge (2720m) was an easy hike.
The way down from the summit was a bit steeper again. The rest was easy again (back at tramway at 4.30pm).
Afterwards I had to drive to Calgary for some business on August 13. So, time for parting company after three very nice days :-( Still there are some unanswered questions: Did they do their backpacking tour? Is Jean-Guy really going up Mt. Robson next year? Will he reach the summit?
