The Expedition Encamped below the Falls of Niagara. January 20, 1679

Executed in oil on canvas, the painting displays a palette dominated by browns, whites, and vivid turquoise. The brushwork varies across the composition: smooth handling characterizes the water and sky, while more textured application appears in the cliff and trees. Snow covers branches and ground throughout the scene. The sky is pale with soft pink-tinged clouds. The artist's inscription G. Catlin. p. appears in the lower right corner, though some sources note the work as not signed, possibly reflecting variations in how the inscription is cataloged. The painting is mounted in a wide tan mat with a small numbered tab at top center. The relatively small scale of the work, under fifteen inches in height, is typical of many pieces in the Cartoon Collection, which Catlin produced in considerable numbers during the later phase of his career.

George Catlin (1796-1872) produced two major collections of paintings during his career. The first, his Indian Gallery, comprised more than 500 works completed during the 1830s, with most surviving examples now at the Smithsonian American Art Museum in Washington, D.C. The second, the Cartoon Collection of more than 600 works created during the 1850s and 1860s, included this painting. When Catlin exhibited the Cartoon Collection in New York in 1871, he published a catalog listing all works with entries that often provided additional information about subjects. The painting's catalog number was 423. The work has been discussed in successive editions of American Paintings and Sculpture: An Illustrated Catalogue published by the National Gallery of Art in 1970, 1980, and 1992. Smithsonian records associate the painting with the topic of United States westward expansion and identify René-Robert Cavelier, Sieur de La Salle as a related subject, placing the work within Catlin's broader series of history paintings documenting French colonial exploration.

As part of the 351-work Paul Mellon gift to the National Gallery of Art in 1965, this painting helped establish one of the most significant public holdings of Catlin's later work. The extensive exhibition history of The Expedition Encamped below the Falls of Niagara demonstrates its role in shaping public understanding of Catlin as a painter of historical narratives, not merely a documentarian of Native American life. The painting's inclusion in the 2013-2014 exhibition On the Trails of the Iroquois at major German institutions indicates its continued relevance in international scholarship on American art and colonial history. Through its preservation and display, the work contributes to ongoing discussions about how nineteenth-century American artists visualized and mythologized the nation's pre-revolutionary European heritage.
