USA HISTORY

Detailed explanation-1: -Expedition from May 14, 1804, to October 16, 1805. Over the duration of the trip, from May 14, 1804, to September 23, 1806, from St. Louis, Missouri, to the Pacific Ocean and back, the Corps of Discovery, as the expedition company was called, traveled nearly 8, 000 miles (13, 000 km).

Detailed explanation-2: -On November 15, 1805, Lewis and Clark and the Corps of Volunteers for Northwestern Discovery reach the Pacific Ocean at the mouth of the Columbia River, one year, six months, and one day after leaving St. Louis, Missouri, in search of the legendary “Northwest Passage” to the sea.

Detailed explanation-3: -In the spring of 1804, Lewis, Clark, and dozens of other men left St. Louis, Missouri, by boat. They traveled westward through what is now Missouri, Iowa, Nebraska, and South Dakota. In November they reached Knife River Village in present-day North Dakota.

Detailed explanation-4: -The route of Lewis and Clark’s expedition took them up the Missouri River to its headwaters, then on to the Pacific Ocean via the Columbia River, and it may have been influenced by the purported transcontinental journey of Moncacht-Apé by the same route about a century before.

Detailed explanation-5: -Lewis and Clark reached the country of the Nez Perce on the Clearwater River in Idaho, and left their horses for dugout canoes. From there they made their way down the Clearwater, Snake, and Columbia rivers, reaching the Pacific Ocean by November 1805.
