Day 3, Morning
The most interesting thing for me in dunes is their texture. I just walk the dunes and collect different textures like a biologist collecting specimens. And sometimes texture leads somewhere like in this case lines of the texture lead into valley. White peaks of Sierra Nevada range are visible in the distance (barely visible on a small picture). It is amazing how such extremely hot and cold places are located so close to each other.
Beautiful picture! I love the texture the sand made.
