There is no question that photography has played a major role in the environmental movement.

My interest in photography did not begin with books or mentors, or with any burning desire to see the world through a camera. It evolved from an intense devotion to mountains and wilderness that eventually shaped all the parts of my life and brought them together.

I find it some of the hardest photography and the most challenging photography I've ever done. It's a real challenge to work with the natural features and the natural light.

A lot of people think that when you have grand scenery, such as you have in Yosemite, that photography must be easy.

Often when I walked alone in the mountains, I tried to make sense out of the two halves of my life. What went on in the city during the week seemed chaotic and unrelated to the events in my mountain world.

We mountaineers always live with the feeling that we came on the scene too late.
