The story "Lewis & Clark Part 2: From The Rockies to the Pacific Ocean and Back" chronicles the arduous journey of the Corps of Discovery led by Meriwether Lewis and William Clark as they traverse the unexplored western territories of the United States. Setting out in April 1805, the expedition faces daunting challenges, from navigating treacherous waterfalls and storms to enduring the harsh conditions of the Rocky Mountains without a known water route. They eventually secured horses through trade with the Shoshone tribe, albeit while suffering from hunger and exhaustion. With assistance from the Nez Perce people, the corps recuperated and pressed on to reach the Pacific Ocean on December 3, 1805. Exhausted, they build Fort Clatsop to winter there amidst relentless rain. The return journey proved easier due to the experience they gained, culminating in a triumphant return to St. Louis on September 23, 1806. The expedition achieved its exploration goal and significantly altered the understanding of the American West.
