Yesterday Marjorie went hiking on a mountain near Marquette where she came across this carving that reads R.S. Chamberlin 10 20 1872. She writes:
Near the highest point of the mountain was a small outcrop of rock. This was carved into it — though it had been hidden by grass and pine needles until one in our party found it by chance and cleared it all away.
PS: Lots more (including a great profile) from Marjorie on Michigan in Pictures!
