Not sure how you could hang one at Trail Camp in a way that would keep marmots off. Outpost Camp has trees so an Ursack could work there - if its allowed.
At trail camp, you have many large boulders with overhanging ledges. I tie a line off of the overhang to a heavy rock up above. This wouldn't stop a squirrel, but you won't find any of them at Trail Camp. The Marmots can't climb down the ropes. Last year, we were in a pretty sheltered spot with lots of tall rocks around us, but none of them overhanging. Here was my solution.
