About Minniehill Falls
I've only visited this waterfall once. It has a real gorge, albeit fairly small. The river has really cut into the rock quite a bit, probably enlargening some existing fractures in the bedrock. For this reason, there isn't a clean flat line at the lip of the falls. This probably dries up in summer, so plan accordingly.
