The minimum slope is 0.5 degrees and the maximum slope is 55 degrees. The median slope is 7.5 degrees and the mode is 10 degrees. Site 21 This site was not mapped as part of the CoastWalkers program. Site 22 This site was not mapped as part of the CoastWalkers program. 5.4 SUMMARY OF POTENTIAL EFFECTS ON THE 22 SITES This section summarizes the information provided above for each site. It is intended to provide the reader with an understanding of the vessel wake effects on the specific beaches. This evaluation is for the current quota and vessel restrictions so the evaluation of a site could change if the number of vessels permitted to enter Glacier Bay proper increases or decreases. See Table 8 for a summary of the overall potential affect to Glacier Bay National Park and Preserve due to vessels. Site 1 Site 1 is generally a sandy beach with some larger material. This means that the beach has a high to moderate potential for erosion. However, the potential for vessel wakes to adversely affect the site at the current quota is negligible. Therefore, this site has a negligible potential for adverse affects at the current quota. Site 2 Site 2 is generally a pebbled beach with cobbles. This means that the beach has a moderate potential for erosion. The potential for vessel wakes to adversely affect the site at the current quota is minor. Therefore, this site has a minor potential for adverse affects at the current quota. Site 3 Site 3 is generally a cobbled to sandy beach that also has a significant amount of boulders and bedrock. This means that the beach has a minor potential for erosion. The potential for vessel wakes to adversely affect the site at the current quota is negligible. Therefore, this site has a negligible potential for adverse affects at the current quota. 29
