The Lewis and Clark journey, also known as the Corps of Discovery, was a historic expedition that took place from 1804 to 1806. The journey was led by Meriwether Lewis and William Clark, who were commissioned by President Thomas Jefferson to explore the western territories of the United States. The expedition aimed to find a water route to the Pacific Ocean, establish trade relationships with Native American tribes, and collect scientific data about the region's geology, flora, and fauna.
Background and Preparation
Before embarking on their journey, Lewis and Clark spent several months preparing and planning. They studied maps, read accounts of previous explorers, and gathered information about the Native American tribes they would encounter. They also assembled a team of 33 people, including a French-Canadian interpreter, a Native American woman named Sacagawea, and her infant son. The expedition was equipped with boats, supplies, and scientific instruments, including a chronometer, a compass, and a quadrant.
Route and Timeline
The Lewis and Clark journey began on May 14, 1804, in St. Louis, Missouri. The expedition traveled up the Missouri River, passing through present-day Kansas, Nebraska, and South Dakota. They reached the Continental Divide in August 1805 and began their descent down the Columbia River, which they believed would lead them to the Pacific Ocean. The journey was not without challenges, including treacherous river rapids, harsh weather conditions, and encounters with hostile Native American tribes.

Key Findings and Contributions
The Lewis and Clark expedition made several significant discoveries and contributions to the fields of geography, geology, and natural history. They collected over 100 plant and animal species, including the prairie dog, the coyote, and the cutthroat trout. They also mapped the Missouri River and its tributaries, providing valuable information for future explorers and settlers.
Encounters with Native American Tribes
The Lewis and Clark expedition encountered over 50 Native American tribes during their journey, including the Mandan, Hidatsa, and Shoshone. They established trade relationships with many of these tribes, exchanging goods such as cloth, metal tools, and guns for food, shelter, and guidance. Sacagawea, who was a Shoshone woman, played a crucial role in facilitating these encounters and helping the expedition to navigate the western territories.
The Lewis and Clark journey also had a significant impact on the Native American tribes they encountered. The expedition's arrival marked the beginning of increased European-American contact and trade, which would eventually lead to the displacement and marginalization of many Native American tribes.
