ZionSlickrock11-12-2011-5

The upper slickrock in Zion National Park is one of my favorite places. While Zion Canyon is truly incredible, the opportunity to play among the petrified dunes of Navajo Sandstone ignites a creative spark that never seems to be extinguished. In the never-ending folds of varicolored rock, waterpockets are often found; and in the right conditions these small pools provide wonderful expressions for the hardrock that shelters them. Late one afternoon in May I found a small pocket deep inside a crevice between two towering dunes, which has eroded slowly over the passing millennia and has formed a repository that only dries up in the midst of the dry season. Its reflecting waters caught the light from the dune high above and created a small view of magic. I knelt in the sand at the edge of the pool and used the lines of the crevice as a reverse-C-curve. This allowed me to use the diagonal lines of the dunes’ surfaces and the shadow cast by the afternoon sun as lines along which the eye could travel. The pines on opposing dunes became frames to direct the eye finally upward to the great dune in the background. The passing clouds added nice touches as actual shapes and as reflections. A focal length of 24mm gave me the angle-of-view I wanted. An aperture of f/22 gave depth-of-field and a shutter speed of 0.8 second at ISO 100 gave an overall medium exposure.
