I'm planning a 4 day backpacking trip next week to Whitney - staying at WP, Outpost, Trail camp, then most likely Trail camp again the night after we summit (unless we go further down). What do people normally leave at Trail camp on summit day? Tent, sleep pad and bag, bear canister? And if so, how do you secure it against the marmots! And also the wind? Is it best to leave it up (it's a Copper Spur 2) or collapse it? Thanks so much.
