Explanation:
Once he was named by President Thomas Jefferson to head the Corps of Discovery, Thermometric Lewis began preparations for the long trip ahead. Much of that preparation involved education; in the months prior to his departure, Lewis would learn astronomy, botany, navigation, medicine and biology, among other scientific disciplines.

In addition, Lewis spent his time accumulating all the supplies that the expedition was going to need. He wrote list after list of provisions, which included guns, ammunition, medical supplies and scientific instruments. While still on the East Coast, Lewis accumulated almost two tons of goods using the $2,500 Congress had allocated for the expedition.
The following list is only a sampling of the supplies taken west by the Corps of Discovery, but it should give a sense of what an undertaking the expedition was.
