Explanation:
Lewis and Clark's expedition added significant knowledge of the zoological and botanical of the continent, providing the first descriptions of many new species of animals, including the grizzly bear, prairie dog, pronghorn antelope, and mountain goat.
Meriwether Lewis, Clark, York, Toussiant Charbonneau, Sakakawea and her son slept together in a tepee the expedition carried. And after the expedition dropped Charbonneau, Sakakawea and her son off at the Knife River Indian villages on the way back to St. ... Louis and bring Sakakawea and the child with him.
Nevertheless, the expedition contributed significant geographic and scientific knowledge of the West, aided the expansion of the fur trade, and strengthened U.S. claims to the Pacific. Clark's maps portraying the geography of the West, printed in 1810 and 1814, were the best available until the 1840s.
Lewis and Clark's team mapped uncharted land, rivers, and mountains. They brought back journals filled with details about Native American tribes and scientific notes about plants and animals they'd never seen before. They also brought back stories—tales that made other Americans dream about heading west.
Their mission was to explore the unknown territory, establish trade with the Natives and affirm the sovereignty of the United States in the region.
