Trail markers

Normally, on the hikes Tom and I take, the trails are marked with little circular signs tacked to trees, or paint blazes on a tree trunk or a rock. But on some of the trails in Acadia, we saw these.


I hadn't seen these before, but apparently they are fairly common on mountain trails and are called cairns (I'm sure many of you already knew that!).

They had a pretty uniform look: two base rocks, a long flat rock connecting them, and a small rock on top of that.


They were plentiful on the Gorham trail, especially near the summit.



And then there were a few that didn't quite make it.

Oops?

But we got the idea anyway.
