Figure 13. Relative Coastal Change-Potential for GBNPP. The colored shoreline represents the relative coastal change-potential index (CPI) determined from the six variables. The very high change-potential shoreline is located along the outer coast where significant wave heights are high and coastal slopes are low. High change-potential shoreline exists at tidewater glacier termini within the fjords and areas along Bartlett Cove where there are large amounts of unconsolidated outwash material. Moderate change-potential shoreline generally lies within Glacier Bay in areas of alluvium or glacial deposits. The low change-potential shoreline is located along rocky areas and sheltered locations in the fjords
