That face carving into the hollow of that tree is pretty cool!

Hmm, I thought about your prompt but didn't really come up with anything. I'm originally from NYC and the only thing I know about things explorers left behind was their name on things. Like Henry Hudson came here from England in the early 1600s and got the river he found named after him.

That's all got! :D SBI please if I even qualify and if I win. Have a great weekend!
