A few months back we took a small road trip looking for locks along the Rideau Canal. It wasn't long before we stumbled upon the Jones Falls Lockstation. The road off the highway was inconspicous, and the parking lot modest. There was a small nature trail leading up to the Stone Arch Dam, although we had no idea how long the trail was or if it was going anywhere.
Coming around the bend, the dam appeared most unexpectedly. We were already at the top of the tall dam, looking downward to the base below - densely covered by trees and brush. It was incredibly impressive, and worth the trip alone, but we continued past to the actual locks. If you look at the map below, we came in at marker 12, then advanced our way down to number one. On the way out, we saw our mistake and pledged to visit the main entrance next time.
