We had an outstanding day in Glacier Bay National Park and Preserve. We woke up next to Margerie, a tidewater glacier that calved off a huge chuck of ice right before we headed into breakfast. We cruised to Gloomy Knob, stopping to watch mountain goats, before heading to South Marble Island. We were surprised when a group of three humpbacks popped up right between us and the island; we didn’t know whether to watch them, the flying puffins, or the noisy Steller sea lions.
