Triple Falls has been a dream of mine for years. It only flows after a heavy rainstorm. I happened to be in Glacier National Park during a very stormy week. One afternoon the waterfall had begun to flow and i stood in the freezing water for about two hours waiting for the rain to stop and the sky to clear. I was soaked to the bone and shivering but I was rewarded. The waterfall only flowed for a very short period of time but it shows that if you want to capture a scene badly enough, you can.
