The journal entries of July 22, 1806 capture the Lewis and Clark Expedition at its most geographically dispersed. Captain Lewis was pushing northwest up the Marias River toward the Rocky Mountain front, hoping to determine whether its waters reached the 50th parallel. Captain Clark was descending the Yellowstone, where his horses had vanished overnight. Meanwhile, Sergeants Patrick Gass and John Ordway — both attached to the party portaging canoes around the Great Falls of the Missouri — recorded a third, smaller crisis: a broken axletree. Reading the four entries together reveals how command structure, literacy, and proximity to events shaped what each narrator chose to record.
Parallel Sergeants: Gass and Ordway on the Portage
Gass and Ordway were eyewitnesses to the same events, and their entries align closely enough to suggest either shared experience or mutual consultation. Both describe men dispersing to search for missing horses, both note the recovery, both record the broken axletree after roughly four to five miles, and both describe the return to the river to repair it. Ordway adds geographic specificity Gass omits — the horses were found “at the grand falls of Missourie” — and quantifies the hunters’ return with game tallies: “three buffaloe and one goat or antelope.”
Gass, by contrast, foregrounds his own experience, noting that he and one other man “did not return till dark” and were caught in a thunderstorm:
Here a heavy shower of rain came on with thunder and lightning; and we remained at this place all night.
Ordway’s entry omits the storm entirely. The divergence is characteristic: Gass, whose journal was prepared for publication, often emphasizes personal narrative and weather drama, while Ordway records logistical and quantitative detail more methodically.
Lewis at the Marias: Geographic Reconnaissance
Lewis’s entry stands apart in register and ambition. Where the sergeants log incidents, Lewis composes a geographer’s report. He describes the gravel that has worn his horses’ feet sore, the absence of timber, the use of buffalo dung for fuel — “I found answered the purpose very well” — and the swelling volume of the river, which he attributes to evaporation and absorption in the open plains. The entry’s intellectual climax is his disappointed admission about the Marias’s northern reach:
I now have lost all hope of the waters of this river ever extending to N Latitude 50°
This sentence carries diplomatic and territorial weight that no enlisted journalist would have written. Lewis was assessing whether the Marias drainage might extend Louisiana Purchase claims north toward the Saskatchewan. His decision to halt at a cottonwood grove ten miles below the mountains — to “rest ourselves and horses a couple of days” and take observations — is framed as scientific necessity rather than fatigue.
Clark on the Yellowstone: Suspicion and Tracking
Clark’s entry is the day’s most psychologically charged. His horses are gone, and over the course of the day his explanation shifts from natural straying to deliberate theft. He dispatches Sergeant Pryor and Charbonneau (“Shabono”) upriver, then widens the search with Shannon and Bratton, and finally suspects Indigenous horse-takers:
begin to Suspect that they are taken by the Indians and taken over the hard plains to prevent our following them.
Clark’s reasoning is empirical. He observes that the horses would not have voluntarily left “the grass and rushes of the river bottoms of which they are very fond,” and that the surrounding plains are too hard to register hoofprints. The entry showcases Clark’s characteristic working method: stating a problem, marshaling evidence, and concluding with an action item — assigning Labiche, who “understands traking very well,” to resume the search at dawn. Where Lewis projects outward onto landscape and continental geography, Clark turns inward to camp management and human motive.
Patterns Across the Four Narrators
The day illustrates a consistent stratification in the expedition’s documentary record. The captains write expansively, each in his preferred mode — Lewis as natural philosopher, Clark as field commander. The sergeants write tersely, with Ordway favoring numbers and Gass favoring incident. None of the four narrators references the others’ situations, a reminder that on July 22, 1806, the parties were operating without communication and would not reunite for several weeks. Only by reading the entries together can the full geography of the day be reconstructed.
