In May of 1804, Capts. Meriwether Lewis and William Clark proceeded
to St. Louis, Mo., in obedience to the following order issued
by President Jefferson by authority of Congress:
Go up the Missouri to its sources; find out, if possible, the
fountains of the Mississippi and the true position of the Lake
of the Woods: cross the stony mountains, and having found the
nearest river flowing into the Pacific, go down it to the sea.
The expedition. - Outfitting in St. Louis, Captain Lewis and
Captain Clark, with four sergeants and twenty-three privates
of the Regular Army, and an Indian interpreter, began the long,
tedious journey up the swift current of the Missouri, reaching
its headwaters approximately one year later. Crossing the Rocky
Mountains, through the Bitter Root Range, they found the Clearwater
River. Proceeding down its course through exceedingly rough country
to tho Snake River, in what is now Idaho, they continued on to
the Northwest to the junction of the Snake with the lordly Columbia.
Launching their canoes upon the broad reaches of this most beautiful
stream in October, 1805, they drifted down to the Pacific Ocean,
reaching their destination November 7, one month later. Returning
from there to St. Louis, with their surveys and maps of the regions
explored, they completed the required journey in a little over
two years' time.
Claim of United States to territory established. - How little
was known of the great domain secured to the United States in
the purchase of the Louisiana Territory is revealed in part by
the wording of the President's order. How much was learned and
its importance to the Nation was contained in part in the report
those two intrepid Army officers gave upon their return. The
most important result obtained was the firm establishment of
the claim of the United States by overland exploration, its first
claim being made through the earlier discovery of this north
Pacific country by Capt. Robert Gray, of Boston, who sailed his
ship from the Pacific Ocean up a great river in 1792, naming
it the Columbia, in honor of the three hundredth anniversary
of the discovery of America by Columbus.
The new country. - The Lewis and Clark expedition gave the people
their first idea of the vast area, enormous natural resources,
and grandeur of the Pacific Northwest. They were the forerunners
of what soon became a mighty host of emigrants into the land
of the setting sun. |
