An accomplishment of the Lewis and Clark expedition was that it recorded information about nature and geography.

Explanation:

The Lewis and Clark Expedition was the United States' first overland expedition to the Pacific Coast and back. The Louisiana land purchase in 1803 sparked interest in extending the United States to the West Coast. A few weeks after buying land President Thomas Jefferson, a westward expansionist, gave US Congress $ 2,500 to send "smart officers with ten to twelve men to explore [the country] to the western ocean." The main objective of the expedition, in addition to the search for a navigable waterway to the Pacific, was the founding of a powerful nation between the Atlantic and the Pacific. In addition, participants should study Indians, animals and plants as well as the geology of the region.
