Lewis & Clark: The National Bicentennial Exhibition brought the expedition into a museum setting where documents, objects and cultural encounters could be studied together. Organized by the Missouri Historical Society, it opened in St. Louis in 2004 before touring nationally. Its lasting interest lies in the questions a display can raise: who made an object, how it survived, and whose account explains its meaning?
An expedition viewed two centuries later
The 1804–1806 expedition crossed territories inhabited and governed by many Indigenous peoples. Its members depended on existing knowledge, food supplies, routes and relationships while pursuing United States ambitions in geography, science and diplomacy. The bicentennial was an opportunity to reconsider both the journey and its consequences.
The Missouri exhibition's contemporary announcement set out a St. Louis run of January 14–September 6, 2004, and a program comparing perspectives on subjects such as trade, geography, plants and diplomacy. The Missouri State Archives' bicentennial commission finding aid (PDF) documents the exhibition within the wider commemoration and confirms its national tour.
The announcement is evidence of curatorial intent and advertised loans. A retrospective also asks what individual collection records establish and how interpretation can continue after a temporary exhibition closes. The surviving exhibition website is labeled a legacy resource; its schedules belong to that historical event.
Follow three objects into their records
The exhibition announcement singled out a letter of credit, Clark's elkskin-bound journal and a preserved woodpecker. The following sources provide routes into those objects and the different questions they support. The Library of Congress material comes from its separate Revealing of America exhibition; it is supplementary documentation, not a checklist proving a loan at every Missouri tour stop.
| Object and date | Record to follow | Question it opens |
|---|---|---|
| Jefferson's letter of credit to Lewis, July 4, 1803 | The Smithsonian's Jefferson display identifies a copy authorizing expedition expenses. | How did government backing support a journey far from its sponsor? |
| William Clark's elkskin-bound field journal, 1805 | The University of Nebraska's Lolo Trail image record credits the Missouri Historical Society's Eleanor Glasgow Voorhis Memorial Collection. | How were routes and observations recorded in the field? |
| Lewis's woodpecker specimen, collected in 1806 | The Library of Congress object description credits Harvard's Museum of Comparative Zoology. | How does a preserved specimen relate to a written description of an animal? |
The journal has a history after the expedition. The National Park Service's account of Julia Clark Voorhis explains that Clark's granddaughter preserved family materials and that the major bequest, including the field journal, reached the Missouri Historical Society in 1923. The route into a collection is part of the evidence, because preservation determines what later readers can inspect.
For the bird, the Library of Congress identifies preserved skin and feathers from Camp Chopunnish, Idaho, in 1806. That record connects collecting, description and later museum custody. A specimen can support observations about a particular animal while leaving many questions about the surrounding ecological knowledge unanswered.
Put Indigenous accounts beside expedition records
An expedition journal records what its writer noticed and chose to explain. Reading it beside an attributed Indigenous account changes the questions. Assistance, trade and diplomacy become decisions made by people with their own histories and purposes.
In Through Nez Perce Eyes, a transcript of a 2001 interview, Nez Perce elder W. Otis Halfmoon discusses names, trade connections and traditions surrounding the encounter. He centers the people who already knew the country and recounts the role of Watkuese in urging assistance. Identify this as an elder's recorded account of community traditions, with its own date and context.
The Nez Perce National Historical Park's account places the expedition in Nez Perce country in 1805 and 1806 and connects the aid it received with the later rupture of relations. For a small comparison, ask what each source makes central: the expedition's immediate needs, the community's decision to help, or the consequences remembered afterward.
Additional bicentennial voices survive through the NPS Tribal Legacy project, associated with the separate Corps of Discovery II touring initiative. Keep the different projects and speakers identifiable instead of merging them into one institutional voice.
Read an exhibition label in four passes
- Identify the thing: record its maker or cultural attribution, date, material and repository. Establish whether it is an original, copy or reconstruction.
- Identify the connection: separate an object carried on the expedition from a later object used to explain its setting or memory.
- Test the interpretation: ask what the physical object and its accompanying records support. Mark where the curator supplies an inference.
- Add another perspective: look for a named community, speaker or source that addresses a question the label leaves open.
Applied to the journal, these steps distinguish Clark's field recording, its later family preservation, modern scholarly presentation and today's reading. Each stage contributes something different to the story.
Continue with a question you can answer
Choose one item and produce a short evidence note: what it is, how it connects to the expedition, what its record establishes and what remains uncertain. Link to the collection record rather than reproducing an image without checking its terms. The journal image record, for example, explicitly calls for reproduction permission.
For another example of comparing accounts made in unequal encounters, see the Moctezuma guide. Its different setting offers a useful comparison of reading methods while retaining the particular history of each encounter.
