It was a cloudless day over the protected marine waters and snowy land of Glacier Bay National Park and Preserve. This was unusual weather for Southeast Alaska, but it was enjoyable. Our first stop was South Marble Island where we saw Steller’s sea lions, tufted puffins, common murres, and floating sea otters. Farther up the eastern side, we slipped into the still, reflective waters of Tidal Inlet. Looking down on us were no less than a dozen mountain goats, scattered and perched on the cliffs. Gloomy Knob gave us more views of sea lions and goats as we cruised up to Margerie Glacier. This is one of the last tidewater glaciers, or a river of ice that flows and calves into the sea. The floating ice is critical for harbor seals who use it for protection from predators. We ended the day with a hike at Bartlett Cove, park headquarters.
