Mt Ipsoot near Pemberton pretty easy trip just your average weekend ski-mountaineering 4000 vertical 15-20km weight haul maybe 40 pounds but if you loose the tent and just take bivy gear thats about 7 pounds off the back. If you loose he camera gear thats another 5 pounds. If you take a summer bag thats another 2 pounds saved. etc
If you like to carry weight over hills you can contemplate this….. a guy I knew carried two 1 pound jars of hot Thai sauce over the Lillooet Icecap on a 3 week ski-mountaineering trip from near the Lord river to Meager Creek….and really didn’t think anything of it. Extremely strong guy big thighs.
