The lewis and clark expedition (1803–1806) was important because it (1) determined the route of the first transcontinental railroad (2) opened an all-water route to the gulf of mexico (3) removed the british threat from the northwest territory (4) increased understanding of the area included in the louisiana purchase

because its important to learn about other countries and how high tech they are compared to us. also its good to learn about other cultures and how ours differs and in common also we need to learn about companies that we still buy since they ship it here.
