I was backpacking in Coyote Gulch, Utah this past week and ran into an issue with my 70 liter backpack. The entrance to the gulch through "Crack in the Wall" was a narrow "slot" entry, so the backpacks could not fit through. Hence we had to lower our packs down the canyon wall with rope while we climbed down separately.
The problem is that abrasion against the canyon wall caused a small rip in the front pocket. So that was annoying because now my bag has a tear in it.
I was wondering what the right way to lower a pack over a canyon wall is--or perhaps more generally, how to deal with reducing abrasion damage to a pack? Is there some sort of covering I should have used for the pack, or is there a certain way to thread the rope through the pack so that it goes down a certain way, etc?
