Quite simply, I love the abstract nature of this image. Knowing exactly what it is and where I shot it, I'm still intrigued as I explore this image. Although by appearance it could be a section of frozen glacier, it's actually a petrified dune in early morning light.

Regardless of the subject matter, it evokes a sense of wonder each time I view it, making it a personal favorite.
