April 30, 1805 found the Corps of Discovery pushing upriver from the recently passed mouth of the Yellowstone, fighting a hard northeast wind across open, nearly timberless country. The four surviving journals from the day — Lewis, Clark, Ordway, and Gass — converge on the same basic facts (an early start, a contrary wind, twenty-four miles made, an elk killed by Captain Lewis, a camp on the north side) but diverge sharply in what each narrator chose to preserve. Read together, the entries expose the division of observational labor that gives the expedition’s record its unusual depth.
The Same Day, Four Registers
Patrick Gass, writing for a future reading public, compresses the day into a single sentence of landscape appreciation and a mileage tally:
We passed through a handsome Country, with a rich soil, and the prairies rising beautifully on both sides of the river. We went 24 miles and encamped on the North side. Captain Lewis killed a large elk here.
John Ordway, the orderly sergeant, gives the same skeleton but fleshes it with the practical detail of a man tracking the commissary. He notes large gangs of buffalo swimming the river that the men deliberately spared — “we would not Shoot them as we had meat enofe on board” — and records a beaver of remarkable size taken at the river’s edge: “a verry large beaver… that would have weighed 70 or 80 pounds, it had large young ones in it.” Ordway also remembers a small detail of seamanship the captains omit, that the party “Sailed a little in the bends of the River this afternoon.”
Lewis and Clark, by contrast, each pursue their own specialized curiosities, and it is in the gap between their entries that the day’s most interesting material lives.
Lewis the Measurer, Clark the Listener
Lewis writes as a naturalist taking inventory. He dismisses the cottonwood timber as “either too small for building, or for plank or broken and dead at top and unsound in the center of the trunk” — a forester’s verdict the others do not bother with. When he kills the day’s elk, his impulse is not to celebrate the shot but to reach for a measuring tape:
I walked on shore this evening and killed a buck Elk, in tolerable order; it appeared to me to be the largest I had seen, and was therefore induced to measure it; found it five feet three inches from the point of the hoof, to the top of the sholders.
Clark, walking the same shore, records something Lewis seems not to have witnessed at all. His interpreter Toussaint Charbonneau and “his Squar” — Sacagawea — accompanied him, and she drew his attention to a flowering shrub:
the Squar found & brought me a bush Something like the Current, which She Said bore a delicious froot and that great quantites grew on the Rocky Mountains, this Srub was in bloom has a yellow flower with a deep Cup, the froot when ripe is yellow and hangs in bunches like Cheries.
This is one of the earliest entries in either captain’s journal in which Sacagawea contributes specific botanical and geographic intelligence — both the identification of the plant (almost certainly the golden currant, Ribes aureum) and the foreknowledge that “great quantites grew on the Rocky Mountains,” a quiet confirmation that the party was now approaching country she knew. Lewis, who would later become the expedition’s principal botanical describer, missed the moment entirely; it survives only because Clark wrote it down.
Cross-Narrator Patterns
Several patterns visible elsewhere in the journals reassert themselves on this date. Gass’s entry is the shortest and most generalized, consistent with his role as a journal-keeper writing for eventual publication rather than scientific record; his “handsome Country” language echoes Clark’s closing line that “the Countrey on both Sides have a butifull appearance,” suggesting Gass may have drawn on Clark’s phrasing or on shared mess-fire conversation. Ordway and Clark agree closely on the wind, the mileage, and the camp’s location, with Ordway adding the buffalo-swim and beaver details that the captains, occupied elsewhere, did not see.
Most striking is the complementarity of the two captains. Lewis catalogs the timber and measures the elk; Clark catalogs the game species (“Antelopes, also Scattering Buffalow, Elk, Deer, wolves, Gees, ducks & Grows”) and records the human exchange that produced a new plant for the expedition’s notice. Neither entry alone captures April 30, 1805. Read alongside Ordway’s commissary eye and Gass’s mileage line, the four journals form a single composite document whose value lies precisely in the differences among its authors.
