It is amazing what you find when you do these backcountry trips. When there is a fire in the backcountry the hotshot crews will be helicoptered in to a ridge or camp location. That sure is a lot of canteens that some crew left behind. You might let the USFS know so maybe somebody will cleanup or not but at least they will be a where they are there. It is interesting how most are rusted but some aren’t. Maybe the rusted ones are tin and the ones that aren’t are aluminum?
That must be a tough hike coming in from White Water. It is too bad that access continues to be closed from Raywood Flats.
