Chamberlain falls and nosestand have changed from back in the 80s. Nosestand was just a calm pool with a perfect funnel to slide up into. Pirouettes were the thing back then. Also, Chamberlain Falls on river left was much more vertical. I had a friend that back endoed into the face of the falls and had a brief fully underwater and upside down vertical entrapment there. I can't see how that would even be possible now.
