Nearly 218 years ago this week, 45 men and one dog set out from Camp Dubois near St. Louis on what was to become one of the most famous explorations in American history. On May 14, 1804, Meriwether Lewis and William Clark led their Corps of Discovery on an expedition to explore the newly acquired western portion of the continent. Their epic two-year journey took them to the Pacific Coast and back, yielding a treasure-trove of detailed maps, climate and soil data, and plant and animal specimens, as well as the beginning of relationships with dozens of tribal nations.
Two of JNPA’s partner sites – Gateway Arch National Park and the Lewis and Clark Visitor Center – feature interpretive exhibits about this famous expedition in their museums. So we thought it fitting to honor the intrepid explorers during this anniversary week.
President Thomas Jefferson commissioned the expedition shortly after acquiring the Louisiana Purchase territory in 1803. Although scientific discoveries and mapping were of high importance, Jefferson’s primary interests were political and commercial. He envisioned an eventual expansion of the nation to the Pacific Ocean and wanted to establish an American presence in the west before European nations made claims to the region. He also charged Lewis and Clark with preparing the way for the extension of the valuable fur trade, with documenting other natural resources that could support future settlements, and with assessing the friendliness of the indigenous tribes they encountered.
Jefferson provided the Corps of Discovery with the best clothing, firearms, boats, equipment, and rations then available. He also supplied them with an assortment of medals, ribbons, needles, mirrors, and other articles which were intended as gifts to Native American chiefs.
The expedition travelled up the Missouri River and through its tributaries in a specially built 55-foot keelboat and two smaller boats called pirogues, averaging 15 miles a day. Their journey proved difficult and exhausting: the men were plagued by heat, injuries, insects, and the river’s strong current and many snags. Both Lewis and Clark’s kept detailed records of these arduous conditions in their journals, which were primarily devoted to meticulous descriptions and drawings of the native people, plants, animals they saw.
To find out more about this famous expedition, you can visit the museum at the Gateway Arch. The Jefferson’s Vision gallery features numerous exhibits on Lewis and Clark’s journey, including replicas and artifacts, interactives about the plants and animals the explorers encountered, and information about the native peoples who inhabited the West at the time of the expedition.
The Arch Store also offers books and other products related to the Corps of Discovery, including the classic best-seller Undaunted Courage by Stephen Ambrose. You can purchase these and other items online or at The Arch Store.
