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.
Of the 40-some on the Lewis and Clark expedition, here are a few of the most memorable: 1  The brilliant but troubled Meriwether Lewis. 2  Out-going and rock-steady survivalist, William Clark. 3  Sacagawea, the Shoshone Indian, child bride, and mother. 4  Sacagaweaâs un-heroic husband, Toussaint Charbonneau.
