Oni, I have to present my subject this afternoon.. I've just begun
Take a look :
Lewis and Clark are two explorers, committed by Thomas Jefferson, the american president, to cross America. They left Saint-Louis on the 14th may, 1804. They were 33 members. Then, they join Lewis in the Missouri. They crossed over the current cities Kansas City (Missouri) and Omaha.(Nebraska). Then they pass through the Rocky Mountains.They descend the cleawater River, then the Snake one and then the Columbia. So this expedition was very hard...
In the winter of 1804–05, the party built Fort Mandan, near present-day Washburn, North Dakota. One chief asked Lewis and Clark to provide a boat for passage through their national territory. As tensions increased, Lewis and Clark prepared to fight, but the two sides fell back in the end.
