Title header for the Tena Bar beach sediment profile diagram.
Hand-drawn cross-sectional geological profile of beach sediment layers at Tena Bar. The diagram shows a layered sediment cross-section with labels indicating: an upper surface of reworked beach sand, a possible postdredging sand layer (marked with a question mark), a dashed line indicating the trench bottom, a clay lump feature on the right side, possible dredge sand, cross bedded sand below, and light color sand at the bottom of the profile.
