Pace up will be easy to moderate with breaks to accommodate early season legs and time to warm up.  Pace down will be faster. Terrain to ski may include slopes like Flue Chutes, Flute backside, and surrounding area.  You ought to be an advanced or expert skier and proficient in basic backcountry travel.  Goal is start early and finish early and be drving back to Vancouver by 230-3pm latest, so very much a 3/4 day but packing water and snacks still warranted. The current weather set up looks encouraging. Will access via creekside lifts so you will need a pass to get on lifts.
