Lewis and Clark had to think ahead and plan for times when wild game would be unavailable or in short supply. Their keelboat was stocked with nearly 7 tons of dry goods, including flour, salt, coffee, pork, meal, corn, sugar, beans and lard.
The Lewis and Clark Expedition was considered a great success, and it did meet its official purpose, as it helped foster an American fur trade. And it also met the other various goals, especially by increasing scientific knowledge and providing more reliable maps. And the Lewis and Clark Expedition also strengthened a United States claim to the Oregon Territory, so the expedition did ultimately lead toward the settlement of the west. 1  The Timeline of the Lewis and Clark Expedition of 1804 to 1806. 2  Free Lewis and Clark Printable Worksheets and Coloring Pages.
