Saltation, creep, and suspension - three different ways sand is moved in the wind, depending on wind velocity and the sand grain size. We were clearly experiencing suspension this morning as the strong breeze carried rivers of sand skimming across the beach on Isla Magdalena. Not to be deterred, we romped across the island, learned of the tenacious flora of the dunes and investigated shells, bones, feathers and a whale carcass rolling in the surf.
