Grindstone Cascade is a long section of the watercourse flowing through Smokey Hollow, below Great Falls. A short 3m high section has been dubbed "the real Grindstone Cascade", however, the full extent of these cascades is much longer and taller. It depends on where the individual chooses to claim that it starts and ends.
