Nearby to Victoria Dam is a hidden waterfall that doesn't have a name.  It's not on many if any maps, but if you know where to look you can find it relatively easily.  I got some valuable intel from a local in the area and set out to find it.  The waterfall is quite impressive!  Easily 30' in height or more as it cascades down a rocky outcrop.

Notably, this waterfall has an exploratory adit beneath it that goes into the hillside a few dozen feet.  It splits almost immediately but otherwise doesn't go very far.  You barely need a light to explore it.  I found a porcupine hunkering in here in the winter once, so I wouldn't plan to use it as a camping spot...
