Early this morning, National Park Service Ranger/naturalist Rebekah, embarked National Geographic Quest at park headquarters, Bartlett Cove. She accompanied us up-bay to relate and interpret the remarkable story of Glacier Bay, including ice advance and retreat, cultural history, geology, and plant succession. We made a slow cruise by South Marble Island to see the nesting birds and hauled-out Steller sea lions, then proceeded to the end of the West Arm (Tarr Inlet), where further travel is blocked by the Margerie and Grand Pacific Glaciers. Margerie was active today and we were thrilled when large sections of this tidewater glacier broke off at the terminus and crashed into the water with a tremendous splash and roar - “white thunder,” making new icebergs in the process. 

We experienced some of the magnificence of Glacier Bay National Park today, and there are many photographs and memories to take home with us.
