Patterns in an endorheic lake, now completely dry, of California's Mojave Desert show the constantly transforming beauty of nature. For me, sustainable travel involves traveling around the world, particularly to support national parks and other wilderness areas that exist to protect our natural resources. This photo was taken as part of an ongoing series I have been working on over the past two years, observing transformations in the natural world with special consideration for issues regarding environmental sustainability. A particular focus of this photo series is water management and water patterns.
