The lodge uses a viewing platform on the Glendale River after August 24th. The platform is located so two sides are the natural river and the third is the entrance to a man-made spawning channel. This third side has deeper water than the river and requires the grizzlies to dive to pick up the dead salmon that have drifted down from the shallower water. This is by far the easiest way to fish for little energy is used for the calories gained. This type of headshake occurs frequently and is likely to clear the water form the ears. Are you are wondering about the forth side to the stands? That would be the walkway to get to the stands.
