The famous exploring expedition under Captains Lewis and Clark wintered at the mouth of the Columbia in 1804-1805, in a group of rude log cabins known as Fort Clatsop. The first settlement in the vicinity was made in 1811, when a fur company organized by John Jacob Astor attempted to establish a trading post upon the Columbia. Two parties were sent out from New York. One travelled by water around Cape Horn, while the other, with great difficulty, crossed the continent by the way of the Missouri, Snake, and Columbia rivers. The undertaking proved unsuccessful, for after the War of 1812 began supplies could no longer be sent safely to the post. The Astor company finally surrendered its establishment to an English company, and in this way the control of the river was transferred to England. With the return of peace the post was restored to the United States, and its location is marked now by the city of Astoria. [Illustration: FIG. 40.--TILLAMOOK ROCK Near the mouth of the Columbia River] What small things sometimes determine the trend of great events! A little more care and energy on the part of Vancouver or Meares would have placed the Columbia River in the hands of the English. The existence of an open river mouth without any breaking bar would have brought about the same result. The Spaniards came first to the Pacific slope, claiming the whole coast as far north as the Russian possessions. Later the United States, by treaty with Spain and Russia, acquired a right to all that portion of the Pacific coast of North America which lies between California and the Russian possessions. But because of the greater energy of the English, and the failure upon the part of the United States to realize the value of this vast region, a considerable section was again lost by the terms of the treaty which made the forty-ninth parallel the boundary line. The intelligence and energy of Captain Gray alone preserved to us the rich lands of Washington.

This barren stretch of country was once marked upon the maps as the Great American Desert, and included a large part of the extensive region lying between the Rocky Mountains upon the east and the Sierra Nevada Mountains upon the west. To the south lay the Grand Canon of the Colorado, while upon the north the boundary was formed by the canons of the Snake and Columbia rivers.
