We started from the Marble Canyon Campground at 6:31AM August 27 2019. We went up Haffner Creek for a couple hours and then went up to the pass between Haffner Mountain and the 2703m peak. We took the ridge to the 2703m peak and then eventually the 3046m peak. We then turned around and went down into the valley opposite Haffner and came out at the Floe Lake trial-head. Lack of trails and lots of dead-fall made this a long day (13h 35min). 24.48km 1703m elevation gain.
