Soaked beach sand glimmers in the sun as the tide recedes. The ripples were left by seaward currents running largely perpendicular to the orientation of the sand ridges. Basically the same process—but on a much larger and slower scale, with wind as the fluid—created the great parallel dune fields of the Nebraska Sand Hills and the Arabian Desert. Bonus: it makes a marvelously sinuous natural artwork!
