Kindler and Strasser [Sediment. Geol. 131 (2000) 1] have identified sedimentary structures of possible aeolian origin within the chevron ridges of north Eleuthera, thereby proposing that they are migrating parabolic dunes formed by wind rather than the impact of giant waves, as postulated by Hearty et al. [Quat. Res. 50 (1998) 309]. However, the abundance of beach fenestrae and the conspicuous absence of foreset bedding throughout the chevron structures invalidate their conclusions. In addition, enormous “megaboulders” situated between the two Kindler and Strasser (2000) study sites in north Eleuthera confirm the occurrence of giant waves at the end of marine isotope substage (MIS) 5e, and argue strongly the same genesis for the chevron ridges and runup deposits.
