Today, I'm very careful not to mention very specific locations when I write or give captions.

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.

When the light is right and everything is working for me, I feel as tense as when making a difficult maneuver high on a mountain. A minute - and sometimes mere seconds - can make the difference between a superb image and a mundane one.

When I go to the mountains, I intuitively know my place in the world much better through these experiences. The more intense they are, the better I know myself, and the more I am able to challenge myself.

And most of my early pictures failed but about one in a 100 somehow looked better than what I saw.

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

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