A sighting of killer whales, announced in this morning’s wake-up call, quickly amassed a crowd on deck that was energetic and undaunted by the 41-degree chill. The energy carried through the day as we explored the nutrient-rich waters of Cross Sound in expedition landing crafts, with sightings of more marine mammals such as harbor seals, Stellar sea lions, and sea otters, in addition to so many eagles we could not keep count.  Afternoon activities ranged from tranquil kayak exploration to soggy bushwhacking, and we spotted humpback whales before bedtime.
