Figure 7. Coastal Geomorphology for GBNPP. The colored shoreline represents the variations in coastal geomorphology within the park. The very high change-potential geomorphology is tidewater glacier termini. High change-potential geomorphology includes gravel and cobble beaches or reworked outwash material. Moderate change-potential geomorphology consists of alluvial fans and glacial deposits along the shore. Low change-potential geomorphology includes medium cliffs and rock platforms, and very low change-potential areas consist of steep rock cliffs.
