The Big Hole River in Montana has three distinct personalities. In its upper reaches, it runs through very gently sloping country and is home to the last remaining river-dwelling population of arctic grayling. A lot of cooperation from ranchers is required to keep the water as pure as required by the grayling. This scene caught my eye years ago, and I was finally able to manage an inviting image from the original capture.
