The exact location of that tower may not be available any longer because of development in the area, and because those who would recall where it was have passed on. Some significant tramping around might locate the footings, but they are likely obscured by foliage, and poison ivy there grows to the size of small trees.
It might be worthwhile to go back and look for more if I had the opportunity.
Then too, the area is one in which the site might be looted by some of the folks who live closest if it was identified, seeking something of value.
I wholeheartedly agree — and obviously, the ultimate origin doesn’t matter, the “loss” of an artifact shows that the Smithsonian couldn’t, and perhaps can’t, be trusted — that it exists not to preserve a heritage, but to preserve a narrative.
