The Source of the Color

The autumn's colors were at their height in the North Cascades National Park. I came across this valley and waterfall and was amazed by colors and how the colors unfolded on their way down the hill. At the top of the image, you can see a collection of autumnal colors which leads its way to the waterfall. It seems that the water is the source of the autumnal colors. And at the bottom of the image you have the burst of colors in response to the end of the line for the waterfall.
