We checked out this area after a brief conversation with a Parks Canada employee (do they call them rangers in Canada?) who gave us the low down on great spots to ski when avy danger was high. She agreed Bow Summit in the trees was solid, and also recommended the trees across from Bow Lake. It was a super quick chat, and the area wasn't in any of the guidebooks or online forums we could find, so we didn't have much to go on, but from checking out topos and satellite images we had a general idea.
We had convinced the only other backcountry skier from the larger group to join us after the super fun day we had Bow Summit, so we were really hoping we didn't end up on another wild goose chase for good turns like we had in a lot of areas around the Parker Hut. Luckily we found a well established skin track right by the pullout across from Bow Lake, and it took us right where we had scoped out on the topo. The kick turns were a little steeper, powdery-er, and deeper than our new ski pal was used to, so it took some getting used to as we climbed up towards the ridge (there may have been an accidental pit dug on one of the sharpest corners as we floundered to get out of the deep pow), but well worth it for the same deep pow on the way down!
It was a short lap, maybe only 30 minutes on the way down.. but a solid find for high avy conditions, and a day when we had a decent chunk of driving (Banff to Revelstoke) ahead of us.
