Perspective view of Heceta Bank

Perspective view of Heceta Bank EM-300 bathymetry data, "looking" southeast, showing smooth wave cut platforms surrounding the ancient shoreline. Rough area is eroded rock outcrop that was above sea level during the lowstand of sea level. Left Inset: Mytilus shell collected at 140 meters during 2001 dive series with ROPOS ROV. Right Inset: Possible human artifact found at the same site. This conical sandstone object is enigmatic, having no obvious natural origin.
