Funny at Laurel Falls TN on the Appalachian trail today in the middle or the stream rocks were stacked about 4 feet high, come the first good rain and they will not be stacked any more.
I have seen carins all over Canada, never really gave them a thought before.
Now what bothers me is trash and I packed out some one else’s Subway cups and sandwich wrappers today. I try to have a plastic bag like you get a WalMart when you buy something just to bring out a little trash if I see it.
