National Park Mystery Photo 35: Big Gear Turning
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.
