I don't know why I continue to do this, or how long I can keep doing it, but there is an amazing sense of concentration when I climb out on this protruding peice of granite, at Glacier Point, Yosemite. I like to stand there for about 10 seconds, just long enough for the person behind the camera I've set up to snap the picture - probably a few seconds longer than it would take to hit bottom should I fall off. My big fear, though, isn't that I'm going to fall - it's that somebody will follow me out and slip and fall off.

I've only made one tough climb at Yosemite - Royal Arches, which leads up from behind the Ahwahnee Hotel - but I don't think any portion of that climb put me more on edge than standing at the edge of Glacier Point does.

The lighting isn't the best with this image - I think early morning or much later in the afteroon would work better, but with photography, as with life, you take what you can get, sometimes.
