Mysterious, photo by Harold Davis. View this photo larger.

What could be more mysterious than a wall of fog or clouds? You never know what is behind: mountains, or a greater storm, or a new life.

Then the veil lifts for a few precious seconds and the tree stands alone but resolute.

Covered again by clouds, the mystery resumes.

I captured this image a couple of weeks ago on my trip to Yosemite with Julian, my oldest son.
