Internal architecture of mixed sand-and-gravel beach ridges: Miquelon-Langlade Barrier, NW Atlantic

Despite the differences in wave exposure along each coast, the sedimentary composition and internal architecture of the two progradational systems are broadly similar; bed dip angles of the individual beach ridges differ by only 1-2°, steeper along the exposed westward-facing coast. Overall, the Miquelon-Langlade beach-ridge plain highlights the primary influences of wave exposure, inherited topography, and proximal sediment sources (from erosion of moraines) on coastal progradational patterns.
