Just as the sun rose in the eastern sky, the National Geographic Sea Lion started its approach to Ice Harbor Lock. Our transit through the lock was the first of a number of activities for the day. About mid-morning, we approached Lower Monumental Lock, with the option of going through in our Zodiacs, which was a unique experience, and enjoyed immensely by all that participated! Continuing our morning cruising the Snake, we approached the Palouse River, the site of our afternoon activities: Zodiac tours, kayaking, and the chance to go to Palouse Falls for a very scenic overlook. Finally, after all guests and staff were back on board, the Sea Lion continued on her way up the Snake, going through our last two locks of the journey, and ending the next morning at Clarkston, Washington.
