I am a new backpacker who is looking to head to Montana to do the 42 mile Gallatin Crest Trail in mid August. Wondering if anybody has done this trail and could provide any advice regarding it? I am particularly concerned about the navigation aspect, as I have heard that the trail can be lost at times, which is why I want to head out there late summer when snowmelt has less likelihood of being a significant problem. Just interested to know anyone's thoughts on this?
