This '2-day' trip is only part of the 5 day trip, and participants are required to sign up for this trip as well as its associated '3-day' trip to Mt Deception. In spite of the technical difficulty being scrambling, I'm limiting the 'first use' of this trip to basic climbing students and graduates to ensure our ability to summit Mt Deception.

Itinerary for entire 5 day trip is as follows (total of ~51 miles and ~13000' elevation gain):
Day One: Via Grand Pass, camp in Cameron Basin (~10 miles, ~3000' gain)
Day Two: Cameron/Lost passes, Thousand Acre Meadows Camp (~10.5 miles, ~2800')
Day Three: Wellesley/Sentinel w/day packs, Cub Creek Camp (~11.7 miles, ~2400')
Day Four: Deception Peak w/day packs (~8.7 miles, ~4600')
Day Five: Dosewallips trail and road to cars (~13.4 miles, ~200')
