USA HISTORY

Detailed explanation-1: -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.

Detailed explanation-2: -What did the Lewis and Clark Expedition Discover? The Lewis and Clark expedition is well known for its discovery of about 122 species of animals, 178 species of plants, numerous Native American nations of the plains and Rockies, and that there was no all-water route to the Pacific Ocean.

Detailed explanation-3: -Lewis had seen great “gangues” of bison on more than one occasion-an estimated 3, 000 near Oacoma, South Dakota, in September of 1804, 10, 000 at the Great Falls of the Missouri on 1 July 1805.

Detailed explanation-4: -Lewis and Clark added to geographic knowledge by determining the true course of the Upper Missouri and its major tributaries, and producing important maps of these areas. They forever destroyed the dream of a Northwest Passage, but proved the success of overland travel to the Pacific.
