Follow the sound until you find the water. You'll start on the trail, touching leaves, balancing on logs, listening for birds. When you arrive at the waterfall, everything drops: cloths flutter down, water pours from cup to cup, objects splash and settle. You're filled with the feeling of downward energy. Along the way, hear the story of a pilot who found the world's tallest waterfall, a schoolteacher who went over Niagara Falls in a barrel at 63, and salmon who never give up.
