Climbed this in the fog in July 1999. The fog lifted for a short little while on the summit so we had a little bit of a view of the Yoho area. A great scramble on relatively (for the Rockies) solid rock although I recall the very last bit as being a little loose in comparison to the rest of the route. Dow's advice about wearing a helmet is definitely to be taken seriously. Approach is easy as there is a highway of a trail to Hamilton lake. From there, the way is obvious.
I made it up 5600' in exactly 4 hours and down in less than 3. There is very little scree on this climb which makes for a pleasant trip. Virtually no one on the trail and of course no signs of humans on the scramble. Several small cruxes along the way but the real crux is the final headwall. This area is loose, wear a helmet and be careful. Cheers.
