We woke to another spectacular day on the Columbia waters. After transiting the McNary Lock and eating a hearty breakfast, we anchored off the Umatilla National Wildlife Refuge where we boarded Zodiacs for our own discovery expedition. This wildlife refuge is extreme important to the spring migration of waterfowl. We saw bald eagles, great blue herons, great egrets, American white pelicans, and many, many other birds. After lunch we had a staff presentation, then entered the John Day Lock, followed by the Dalles Lock at cocktail hour. We enjoyed the changing landscape of the Columbia River as we transitioned toward temperate northwestern forest.
