When I first noticed these ridges in the sand I thought they looked like tiger stripes. So taking Doug's advice to heart I attempted to pump up the constrast and color and move the image in the tiger direction. I used the Photo Filter adjustment layer in Photoshop, with the Warming filter (LBA) and increased the density in that menu to 83%. Then I duplicated that layer to make it more intense and added a Curves layer for more contrast.
