On March 28, 1805, the Corps of Discovery stood on the edge of departure from Fort Mandan. The Missouri was breaking apart, the pirogues were being readied, and the Mandan villagers were turning their attention to the river’s seasonal harvest. Two journalists—Sergeant John Ordway and Captain William Clark—recorded the day, and the contrast between their entries illuminates the division of observational labor that characterized the expedition’s record-keeping.
Parallel Labor, Divergent Registers
Ordway’s entry is brief and crew-focused. Writing from the perspective of the working party, he notes the weather and the men’s tasks in a single compact sentence:
night, a pleasant morning. The Ice continues to run. the party employed fixing their perogues oars and poles, So that we may be ready to set out as Soon as the Ice is done running.
The sergeant’s prose is functional, oriented toward readiness. His vantage is that of a man among the workers—”the party employed”—and his temporal horizon extends only as far as the next milestone: the moment the ice stops running and the boats can launch.
Clark, by contrast, produces two overlapping entries for the same date, and together they sprawl across weather, carpentry, river ice, Mandan ethnography, and zoology. His shorter notation records the technical work:
28th had all the Canoes, the Perogus corked pitchd & lined cover the Cotton Wood, which is win Shaken
His fuller entry expands the same observation with greater precision—”corked pitched & tirred in and on the cracks and windshake which is universially in the Cotton wood”—and adds meteorological detail absent from Ordway: “a windey Blustering Day wind S W ice running the river Blocked up in view for the Space of 4 hours and gave way leaveing great quantity of ice on the Shallow Sand bars.”
Where Ordway calls the morning “pleasant,” Clark calls the day “windey Blustering.” The discrepancy is not necessarily contradictory—Ordway wrote of the morning, Clark of the whole day—but it illustrates how rapidly conditions shifted on the upper Missouri in late March, and how each man fixed his observation to a different slice of the day.
What Clark Sees That Ordway Does Not
The most striking difference between the two narrators on this date lies in what Clark records that Ordway omits entirely. Clark twice turns his attention to Mandan practice. First, in a parenthetical aside about cottonwood, he notes:
(the Mandans feed their horses on the cotton wood Sticks in places of corn)
This is the kind of ethnographic aperçu that surfaces repeatedly in Clark’s Fort Mandan winter writing—an observation triggered by the Corps’ own use of the same tree for boat repair. The cottonwood is simultaneously a structural material for the Americans and a fodder substitute for the Mandans, and Clark registers both functions in a single entry.
His second ethnographic note is more arresting still. Clark observes that few Indians visited the fort because they were occupied at the river:
they are watching to catch the floating Buffalow which brake through the ice in Crossing, those people are fond of those animals tainted and Catch great numbers every Spring
The detail is remarkable on multiple counts. Clark documents a seasonal subsistence practice—the spring harvest of drowned bison swept downriver after falling through weakened ice—and notes without judgment the Mandan preference for the meat in its tainted state. Ordway’s silence on this practice is characteristic; the sergeant rarely strays from the immediate concerns of the working detachment, while Clark, as a captain charged with intelligence-gathering, treats the day’s interactions with the Mandans as data worth preserving.
The Shape of the Record
Read together, the two entries demonstrate how the expedition’s documentary record was layered rather than redundant. Ordway confirms the timing and nature of the work; Clark confirms the same and adds the environmental, technical, and cultural context that gives the day its texture. The shared elements—ice running, boats being prepared, departure imminent—anchor the date. The unshared elements—wind direction, the windshake in the cottonwood, Mandan horse-feeding, the floating buffalo—belong to Clark alone among these two voices, and would be lost to the historical record had he not written them down.
The contrast also previews a pattern that will hold through the journey ahead: Ordway as the steady chronicler of the Corps’ internal life, Clark as the broader observer of the world through which the Corps moved.
