The bark close up bark photo reminded me of topography and earth forms seen from space. So I thought, what would happen if the bark became the land forms of a mountainous mapping project. Voila Barkle Earth. A simple 90 degree rotation of the image and some work with a bit of color and we have a whole new terrain to explore. This was a blast! I like the way the lighter areas of the bark read like granite striations and above treeline elevations.
