Where did the Lewis and Clark expedition take place?

The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was an expedition that took place in the United States from 1804 to 1806. The expedition was authorized by President Thomas Jefferson and led by Meriwether Lewis and William Clark. The expedition's main purpose was to explore the newly acquired Louisiana Territory, which had been purchased from France in 1803. Lewis and Clark's party traveled up the Missouri River, crossed the Rocky Mountains, and reached the Pacific Ocean. Along the way, they encountered many different Native American tribes and learned about their cultures. The expedition was a success, and its results helped to inform the U.S. government about the geography and resources of the newly acquired territory.
