It's a big gear turning, but where in the National Park System will you find it?
Having been embarrassed by how easily the last was solved, we think we've made this one a little more difficult. The question is, have we? To prove us wrong, you need to identify what this is, and in which unit of the park system you can find it.
The answer, of course, will be provided tomorrow.

Looks like it could be part of a mill works?
How about Peirce Mill in Rock Creek Park?
No, not Rock Creek Park.
Pipe Spring NM?
Nope, not Pipe Spring.
Is it at Saugus Iron Works NHS?
No, not Saugus either....
I give up if this one is wrong--Lowell?
