That's pretty intriguing to look at. The proportion of the holes (longer than wide) and irregular spacing caught my eye. Just for fun I'd guess it's a predatory pattern in which a creature dives under the sand (first small crater hole at bottom of the photo) burrows for a bit, and then emerges to capture prey, then reenters the same hole, burrows for a bit to where there's not such an obvious disturbance in the surface, and repeats the hunt. The comparatively wide dispersal around the holes could be a sign of a high-velocity leap...
