Chaos Creek as it flows out of Lake Haiyaha in Rocky Mountain National Park, Colorado.
I was very fortunate to be accompanied on this hike by Jown Ward who is a master at large format, Black & White film photography. He took me on his "bushwhack" winter trail to the lake. We saw several differant instances of Bobcat tracks as well as one set of quite fresh Black Bear tracks through the snow.
Here is a link to John Ward's latest book on Amazon. I highly recomend it.
