where did the lewis and clark trail end
Lewis and Clark Expedition On the south side of the Columbia River, 2 miles (3Â km) upstream on the west side of the Netul River (now Lewis and Clark River), they constructed Fort Clatsop.[55] They did this not just for shelter and protection, but also to officially establish the American presence there, with the American flag flying over the fort.[48][59] During the winter at Fort Clatsop, Lewis committed himself to writing. He filled many pages of his journals with valuable knowledge, mostly about botany, because of the abundant growth and forests that covered that part of the continent.[60] The health of the men also became a problem, with many suffering from colds and influenza.[57]
Northwest Territory The region was assigned to the United States in the Treaty of Paris of 1783, but sporadic westward emigrant settlements had already resumed late in the war after the Iroquois Confederacy's power was broken and the tribes scattered by the 1779 Sullivan Expedition. Soon after the Revolution ended, land-hungry migrants started moving west. A gateway trading post developed as the town of Brownsville, Pennsylvania, which was a key outfitting center west of the mountains. Other wagon roads, such as the Kittanning Path surmounting the gaps of the Allegheny in central Pennsylvania, or trails along the Mohawk River in New York, enabled a steady stream of settlers to reach the near west and the lands bordering the Mississippi.[a] This activity stimulated the development of the eastern parts of the eventual National Road by private investors. The Cumberlandâ€“Brownsville toll road linked the water routes of the Potomac River with the Monongahela River of the Ohio/Mississippi riverine systems in the days when water travel was the only good alternative to walking and riding. Most of the territory and its successors was settled by emigrants passing through the Cumberland Narrows, or along the Mohawk Valley in New York State.
