Aerial photograph of the Escollo de Arenas, a subtidal sand and gravel deposit that extends some 6 kilometers north-northwestward of Punta Arenas on the northwest coast of Vieques Island, east of Puerto Rico. Sinuous bedforms extending parallel to the axis of the shoal (and normal to the direction of tidal currents) are sand waves with wavelengths of about 100 meters and amplitudes of 2-3 meters.
