Nassagaweya is definitely a favourite location. Did you approach from Walker's Line, Crawford Lake or Rattlesnake Point?
Nice photo with good detail and dynamic range. I find the title a bit of a misnomer, though, as there is barely a hint of mist. You are setting up an expectation that is not fulfilled by the photograph.
I don't mean to be harsh, but I also find the composition rather direct and unimaginative with the central placement of the cascade rather formally framed by rock and trees.
I love the receding forest along the top and I would think something more could be done to create a three-dimensional dynamic with the trees, rocks, cascade and forest.
