The sign is pretty much self explanatory.

A brief history of the Fire Tower on top of Hadley Mountain.

It's a gentle down hill and up, although walking on all the exposed rock on the way down is rough on the ankles. The trail obviously gets a lot of use.

Back when the Fire Tower was actively used for surveying fires, in the era-prior the mid-1980s, the ranger would have lived here.

This sign was on a building by the now abandoned Ranger's Station.

I didn't dare open it. I can only guess why the door is propped closed.
