Here the explorers had their last portage. On the second day of November they reached the foot of the Cascades and perceived the movement of the tide, which made it plain to them that the ocean was near at hand. Yet, in reality, it was much farther than they thought, for the majestic lower River extends one hundred and sixty miles from the foot of the last cataract to the Pacific. It is interesting to notice comments made by the explorers upon the green and fertile islands at the lower end of the Cascades, and that spired and turreted volcanic cliff which they called Beacon Rock, but which we know now as Castle Rock. The rest of the journey of Lewis and Clark was a calm floating down the tranquil flood of the lower Columbia in the midst of the fog and clouds which at that season of the year generally embrace all objects. On November 7th the mist suddenly broke away before them, the bold mountainous shores vanished in front, and, through the parted headlands, they looked forth into the expanse of the ocean.

They had demonstrated the possibility of crossing the continent and of linking together the waters of the Missouri and the Columbia. The winter of 1805-06 was spent in log buildings at a point named by the explorers, Fort Clatsop, situated on the Lewis and Clark River at the south side of the Columbia a few miles from the present site of Astoria. The location of this fort has been identified in modern times, as has also the location of the salt cairn, upon what is now known as the Seaside Beach, commemorated by an inscription. One of the interesting little human touches in the narrative of Captain Lewis describes the casting of a whale upon Clatsop Beach and the journey of the party to see the great marine curiosity, as well as to secure some of its fat and blubber. The Indian woman, Sacajawea, was to be left behind to keep camp while they were all at the beach, but she put up the earnest plea that inasmuch as she had never seen any such curiosity as the "big fish," and as she had journeyed all those weary miles from the country of the Mandans, it seemed hard that she should be denied the privilege of satisfying her eyes with a view of the whale. Lewis remarks that the request of the poor woman seemed so reasonable that they at once fixed up camp in such manner that it could be left, and took her with them, to her intense satisfaction. After four months spent in the fogs and mists of the coast, and without seeing any of the ships which the Indians said were accustomed to come in considerable numbers during the spring and summer, the party turned their faces homeward on the 23d of March, 1806. The commander posted upon the fort a notice which read as follows:
