The journey of Meriwether Lewis and William Clark, famously known for their Corps of Discovery Expedition, began in Pittsburgh, Pennsylvania. Their time in Pittsburgh was a critical starting point for the historic exploration that would chart the vast, uncharted territories of the Louisiana Purchase and beyond.
In 1803, President Thomas Jefferson commissioned Meriwether Lewis to lead an expedition to explore the newly acquired lands west of the Mississippi River. Pittsburgh, a burgeoning frontier town known for its boat-building industry and strategic location at the confluence of the Allegheny and Monongahela Rivers, was selected as the departure point for the expedition.
Meriwether Lewis arrived in Pittsburgh on July 15, 1803, with the primary goal of supervising the construction of a keelboat that would carry the expedition’s supplies and men down the Ohio River. The construction of the keelboat, which was about 55 feet long and designed for shallow waters, proved to be more time-consuming and problematic than anticipated. Delays were caused by a variety of issues, including logistical problems and the inexperience of the boat builders with such a specific and demanding project.
Despite these challenges, Lewis used his time in Pittsburgh effectively. He procured supplies and equipment, gathered additional men to join the expedition, and continued his preparation for the long journey ahead. Lewis also took advantage of Pittsburgh's position as a frontier town to acquire valuable knowledge and resources that would be essential for the expedition’s success.
Finally, on August 31, 1803, the keelboat was ready. Lewis and his small crew set off from Pittsburgh, embarking on a journey that would take them down the Ohio River to join forces with William Clark and the rest of the Corps of Discovery. They made their way through the rough waters and treacherous currents, stopping along the way to recruit more members for the expedition and gather additional supplies.
Pittsburgh’s role in the Lewis and Clark Expedition was pivotal, as it marked the official beginning of the ambitious endeavor to explore and map the western territories of the United States. The city provided the essential launchpad for the Corps of Discovery, offering resources, expertise, and a strategic starting point that set the stage for the historic journey.
Today, Pittsburgh honors its connection to this significant chapter in American history. The Senator John Heinz History Center, in particular, features exhibits that highlight the early days of the expedition, showcasing artifacts and stories from Lewis's time in the city. The center's displays provide visitors with a glimpse into the challenges and preparations that took place in Pittsburgh, underscoring the city’s crucial role in the epic exploration.
