Answers to Your Questions

by Dayton Duncan

Ken Burns and I have been deeply gratified by the overwhelming public response to our PBS documentary, "Lewis & Clark: The Journey of the Corps of Discovery," and its companion book. We've also been bowled over by the flood of interest in this web site. We're both glad to see all the enthusiasm that has been sparked about the Lewis and Clark expedition.

We can't answer each one of the factual questions that have flooded in, but I'll try here to address some of the mostly commonly asked ones. (Many of them are answered in our companion book, Lewis & Clark: The Journey of the Corps of Discovery, published by Knopf and available in most bookstores, online at shopPBS or by ordering through PBS at 1-800-424-7963. And others can be found in some of the many scholarly books about the expedition, listed in our book's bibliography and reprinted at the end of this message.)

Question: What happened to Sacagawea's children?
Jean Baptiste Charbonneau -- "Little Pomp" to William Clark -- was educated in St. Louis under Clark's supervision and later became a traveling companion to a German prince, who took him to Europe for five years, where he learned several languages. Baptiste returned to America and for awhile became a mountain (the explorer John C. Fremont mentions in his journals encountering him.) During the war with Mexico in 1846, Baptiste was hired by the Army to guide the Mormon Battalion from Fort Leavenworth, Kansas, all the way to California, where he became a magistrate of San Luis Rey Mission in California after the conflict. In 1866, at age 61, he learned of gold discoveries in Montana and set off with a wagon train for the gold fields, but caught pneumonia along the way and died on May 16 in southeastern Oregon. A historical marker near the town of Danner marks the spot. I'm unaware of any information about the fate of Sacagawea's daughter, Lisette. More information about Baptiste (and Sacagawea and Toussaint Charbonneau) is available from a pamphlet published by the Fort Clatsop Historical Association, "A Charbonneau Family Portrait," by Irving W. Anderson. (Fort Clatsop National Memorial -- 503-861-2471 -- sells it in their bookstore.) Anderson's pamphlet also examines the two competing theories about the time and place of Sacagawea's death. He concludes (as do most historians) that it was December 20, 1812, at Fort Manuel near today's Kenel, South Dakota; not many years later, at the age of 100, on the Wind River Indian Reservation in Wyoming.

Question: What happened to Lewis's dog -- and what was his name?
For many years, scholars believed the Newfoundlan's name was Scannon, until 1984, when Donald Jackson (one of the pre-eminent Lewis and Clark historians) noticed a stream in one of Clark's maps clearly designated as "Seaman's Creek." He went back to the original journals, studied the handwriting, and determined that what previous editors had believed was "Scannon" was instead "Seaman." (As a name for a Newfoundland, Seaman also makes more sense than the inexplicable Scannon.) Seaman is not mentioned in the journals after July 15, 1806, on the return trip, when Lewis was at the Great Falls and notes that his dog was being plagued by mosquitoes. So, from the written record, we can't say for sure what happened to him. But I firmly believe -- as do most expedition scholars I know -- that Seaman made it back to St. Louis with the rest of the Corps of Discovery. Why? Because it is inconceivable that the dog's death, disappearance, or abandonment would have gone unremarked in the journals of Lewis, Clark, or any of the other men. There's a fuller discussion about Seaman -- his role in the expedition and adventures on the trail -- on pages 26 and 27 of our companion book. And even more in a supplemental publication of We Proceeded On , the official publication of the Lewis and Clark Trail Heritage Foundation, Inc. The supplemental publication is "The Lewis and Clark Expedition's Newfoundland Dog," and includes two monographs by Ernest S. Osgood and Donald Jackson.

Question: Where can I get more information about the modern Lewis & Clark Trail?
First, Ken and I would urge anyone who wants to become more involved with Lewis and Clark to join the Lewis and Clark Trail Heritage Foundation, Inc. It is a national group dedicated to keeping the story of Lewis and Clark alive and to stimulating public interest in expedition's journey and the trail they followed. They have local chapters along the route; meet as a national group every summer at a different spot on the trail (1998 in Great Falls, Montana); and publish a magazine several times a year called We Proceeded On . Information about the group is available by writing them at P.O. Box 3434, Great Falls, MT 59403 or online, I think the best guidebook for anyone planning a trip along the trail is The Traveler's Guide to the Lewis & Clark Trail, by Julie Fanselow (Falcon Press, 1994). Another one is Lewis & Clark: Historic Places Associated with Their Transcontinental Exploration, by Roy Appleman. Fanselow's is a straightforward guide book, with highway routes, other attractions, etc. Appleman's, first published by the National Park Service, devotes half its space to a good summary of the expedition's story and its second half to an annotated listing of the principal historic sites along the route.

Question: What part of the modern trail is the most unchanged?
Without a doubt, the most unchanged section of the entire Lewis and Clark route is White Cliffs section of the Missouri River in north-central Montana -- a stretch of the river, now protected by Congress, that is only accessible by boat (usually canoe). This is the place, with its eerie sandstone formations, that Lewis wrote his famous line about "scenes of visionary enchantment." More information about that part of the Lewis & Clark trail is available from Travel Montana, 1-800-847-4868 (1-800-VISIT-MT) or online, at

Question: Where are the original journals housed?
Most of the journals of Lewis and Clark (and Sgt. John Ordway) are at the American Philosophical Society in Philadelphia. Some additional Clark journals are at the Missouri Historical Society in St. Louis and at Yale's Beinecke Library. Sgt. Charles Floyd's brief journal is at the State Historical Society of Wisconsin; and Private Joseph Whitehouse's is at the Newberry Library at the University of Chicago. Sgt. Patrick Gass published an edited version of his journals shortly after the expedition's return, which can be found in many libraries, but his original, handwritten journals have not been located. Dr. Gary E. Moulton is completing a multi-volume edition of the complete journals for the University of Nebraska Press -- 11 volumes published so far, with one or two more left and about to come out. The publisher's number is 1-800-755-1105.

Question: How did Lewis & Clark communicate with Indian tribes?
It depended on the situation. During the first year, they often had interpreters (usually French-Canadians) who also spoke the Indians' language -- for instance with the Otos, the Yankton Sioux, the Arikara, the Mandan and Hidatsa. Sacagawea was obviously crucial in the translating chain with her own people, the Shoshones. But in many instances, the explorers relied on the skills of George Drouillard, who knew sign language -- a rudimentary way of communicating through gestures, practiced between the many different western tribes who rarely spoke the same language.

Question: Are there still any of the peace medallions?
Both the Oregon Historical Society and the Holland Library at Washington State University have medals that Lewis and Clark gave to Indian chiefs they met. Replicas are available from the United States Mint. Yale's Beinecke Library has a copy of the paper certificate that the captains distributed to so-called "lesser chiefs."

Question: How can I find out more about the Spanish government's attempt to destroy the Lewis and Clark expedition?
The best source is "A Moment in Time: The West -- September 1806," by Dr. James P. Ronda, in "Montana: The Magazine of Western History," Vol. 44, No. 4 (Autumn 1994).

Question: How could they have seen pheasants, since the birds weren't introduced to North America until many years after the expedition?
They didn't see any pheasants, but they used the word several times in describing other birds, usually grouse.

Question: How did Lewis and Clark get mail -- and the prairie dog -- back to Jefferson?
Very, very slowly! News and mail worked its way east from St. Louis overland and by water. During the journey itself, the last batch of information from the Corps of Discovery was sent downriver with the big keelboat from the Mandan villages in April of 1805, while the captains and most of the others headed farther west. Included in the shipment was the live prairie dog the explorers had captured in South Dakota during the summer of 1804 and had kept alive in a cage in Fort Mandan. The prairie dog -- and everything else: reports, animal skins, Indian corn, etc. -- was taken by the keelboat to St. Louis, put onto another boat going down the Mississippi to New Orleans, then put onto a sea-going vessel from New Orleans to Washington. It all arrived in August of 1805 -- on the same day Lewis was ascending Lemhi Pass nearly three-quarters of a continent away. (Jefferson later sent the prairie dog to a natural science museum set up in Independence Hall in Philadelphia, where it apparently died not too long after being put on display.) Between April 1805 and September 1806 -- when Lewis and Clark traveled from the Mandan villages to the Pacific, then back all the way to St. Louis -- there was no means to send any interim updates on their progress. Lewis wrote to Jefferson on the same day of the expedition's triumphant return to St. Louis, Sept. 23, 1806; it took nearly a month to reach the President.

Question: Are there any replicas of the expedition's keelboat?
There used to be two (and we filmed them both for the documentary); now there's one, but soon there will be two again. One is at Lewis and Clark State Park near Onawa, Iowa, and it's on display on an old oxbow of the Missouri roughly between Memorial Day and Labor Day. More information about events, etc., are available from the park at 712-423-2829. Another fine replica was constructed by volunteers in St. Charles, Missouri, but it was destroyed in a warehouse fire last winter. They have already built a replica of one of the expedition's pirogues and are raising money to rebuild a keelboat capable of going long distances up the Missouri. More information about the St. Charles Lewis and Clark Rendezvous events and the keelboat and pirogue at 314-946-7776.

Question: Where I can find genealogical information about the expedition?
The Lewis and Clark Trail Heritage Foundation has a genealogy committee. Contact them through the Foundation at P.O. Box 3434, Great Falls, MT 59403, or online at
