Corps of discovery: Lewis & Clark expedition.

The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was

the first American expedition to cross what is now the western portion of the United States, departing in May, 1804 from St.

Louis on the Mississippi River, making their way westward through the continental

divide to the Pacific coast.

Thomas Jefferson was the one, who sent those two

army captains to Louisiana

On November 7. 1805 Lewis and Clark reached the Pacific Ocean

They returned to St. Louis on September 23, 1806.

They justified the possibility to travel west as far as the Pacific Ocean by land.

As a result, pioneers began moving westward to the Pacific coast.

Although the expedition did make notable contributions to science, scientific research itself was not the main goal of the

mission
