Detailed explanation-1: -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 May 14, 1804, Meriwether Lewis, William Clark and their group of 40 men, collectively known as the Corps of Discovery, launched their pirogues and keelboat onto the Missouri River at its mouth, some 18 miles from the young town of St. Louis.

Detailed explanation-3: -After reaching the Pacific Ocean in November 1805, the corps established Fort Clatsop, near present-day Astoria, Oregon, as its winter quarters.

Detailed explanation-4: -WAY OUT WEST 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.

Detailed explanation-5: -Louis is considered the Gateway to the West, and there’s a reason for that. On May 14, 1804, William Clark and his Corps of Discovery departed from a fort near St. Louis at the Mississippi River to begin a two-year exploration of the land acquired in the Louisiana Purchase.
