Martin Siddles and I scrambled up and down the standard scramble route (NE ridge). No snow and very hot for June 1.
I climbed Mt. Fullerton solo and found discrepancy with the Canadian Rockies Scrambles Book. I ascended via the NW ridge and descended via the East-SE Ridge. It worked and I recommend it for a full traverse of the mountain. I climbed on Canada Day and the campground was stuffed full, but the only folks I ran into getting through the campground to the trailhead were smoking cigs and did not look like they were going to hop on the trails anytime soon. I did not see a soul on ascent, and very few on the trail out either. If you are allergic to people, as I am, no worries about them filling up the backcountry. They will more than likely stay in the campground where they can drink beer and eat hot dogs. Thank goodness our hobby is not so popular. Cheers!
