Toured to Crowfoot Pass today, April 18, via the "Creek Route" (page 166, Ski Trails in the Canadian Rockies, 3rd edition). We parked on the highway adjacent to the creek and skied directly to it and that was fine through open timber. Supportive melt freeze crust the whole way with 10 cm of new snow on top of it above treeline, great traveling. Had 2 whumpfing settlements on the flats leading into the col, a wind scraped melt/freeze crust dropping into the basal facets would be my guess. Great ski quality on the way down. The crust was supportive all the way back to the road with the only dropping to ground happening 50 cm away from the highway at 1 pm.
A good tour.
Happy trails,
