Early in the morning, we transited the Ice Harbor Dam on the Snake River dropping approximately 100ft and then had a lovely brunch. We arrived at the confluence of the Snake and Columbia rivers and took Zodiacs ashore to the Sacagawea State Park. The Confluence area was significant to the Indigenous people of the region for millennia as a place to gather and trade. This particular spot was also historically significant to the Lewis and Clark Expedition, which camped here in October of 1805 and surveyed the confluence area. Half of us started with a visit to the REACH Museum with exhibits on the natural, cultural, and scientific history of Hanford Reach and the Columbia Basin area, while the other group took in Sacagawea State Park, the interpretive center, and the Confluence Project installation by Maya Lin. We then switched so everyone could enjoy both sites.
