We will use some of the biggest tidal changes of the year to help sweep us down from Skamokawa to Pillar Rock and back along the rugged Columbia north shore. Here the Columbia broadens into an impressive expanse. On the shore directly opposite Pillar Rock is the site where Lewis & Clark camped the night of November 7, 1805. There Clark wrote, "Great joy in camp we are in view of the Ocian, this great Pacific Ocean which we been So long anxious to See." The rock itself is a famous landmark, a pillar of basalt rising from the 40-foot deep channel. The old Pillar Rock Cannery still stands on the shore nearby. After lunch on a scenic sand beach we will return along the coves and bluffs of the north shore.
