The journals of August 6, 1805 converge on a single compound disaster at the junction of the Big Hole and Jefferson rivers. Clark’s detachment, hauling the canoes upstream, had taken the wrong fork because Lewis’s note — affixed to a green willow pole — had been felled and carried off by beaver. By the time Drouillard reached Clark with corrected directions, the party was already several miles up the rapid northern branch and had to retreat down the same shoals they had just labored up. The descent cost them three swamped canoes, roughly twenty pounds of spoiled powder, the contents of the medicine box, and very nearly the life of Joseph Whitehouse.
The Same Accident, Five Camera Angles
The capsizing is the day’s narrative gravity well, and each narrator frames it differently. Gass, characteristically terse, gives only the inventory:
a knapsack, shot-pouch and powder-horn lost, and all the rest of the loading wet.
Ordway expands the catalog and adds a second near-miss —
one canoe turned over another partly filled and was near turning over also
— and is the only narrator who names the injured man in the third person:
one man Jos Whitehouse got his leg lamed when the canoe turned over.
Whitehouse himself supplies what no other journal can: the first-person mechanics of the accident. He was in the stern; he jumped out to right the boat; the current swung her around and pinned him.
caught my leg under hir and lamed me & was near breaking my leg.
Lewis, who was not in the canoe but reconstructed the event afterward, supplies the margin of survival with chilling precision:
the canoe had rubed him and pressed him to the bottom as she passed over him and had the water been 2 inches shallower must inevitably have crushed him to death.
Whitehouse, writing of his own body, does not mention the two inches. Lewis, writing of his man, does. The detail likely came from someone in the canoe and was filtered through the captain’s habit of quantifying everything.
The Whitehouse-from-Ordway pattern is visible here in its usual form — Whitehouse’s opening sentences track Ordway’s nearly verbatim (“we Set out as usal, and proceeded on hall[]ing the canoes up the rapids. the bottoms low and covered with Small timber”) — but the accident itself breaks the pattern. On a matter where Whitehouse had direct experience, his prose departs from Ordway’s and becomes specific, physical, and his own.
The Beaver, the Panthers, and the Lead Canisters
Two causal details appear only in the captains’ entries. Clark alone explains the wrong-fork error:
this lettr was Cut down by the beaver as it was on a green pole & Carried off.
He pairs this with a second small predation —
Three Skins which was left on a tree was taken off by the Panthers or wolvers
— a doubling of animal interference that the enlisted journals omit entirely. Lewis confirms the lost skins in the truncated tail of his entry but spends his analytical energy elsewhere: on the lead canisters of powder, his own invention, which had survived more than an hour underwater intact.
about 20 lbs. of powder which we had in a tight Keg or at least one which we thought sufficiently so got wet and intirely spoiled.
Lewis uses the disaster to vindicate his packaging system, noting that the dry plains air shrinks even seasoned wood unless kept full of liquid. None of the sergeants register the canister question; for them the powder is simply lost or saved.
What Each Narrator Preserves Alone
Gass is the shortest and contributes the cleanest summary of the route reconnaissance — that the party had gone “5 or 6 miles up the north branch” before turning back. Ordway alone records that George Shannon failed to return that evening and that the party
blew the horn and fired Several guns in hopes he would hear it
— the beginning of Shannon’s second extended disappearance of the expedition. Whitehouse alone gives the interior view of the capsizing. Lewis alone gives the medical margin and the powder-canister vindication. Clark alone names the beaver as the agent of the original confusion and adds, almost as an aside, that his ankle is
much wors than it has been
— an injury threading through several entries this week that the enlisted men do not mention.
Read together, the five accounts reconstruct a chain of small contingencies — a green pole, a hungry beaver, a missed note, a wrong fork, a hauled retreat, a swung stern, two inches of water — that came within a hand’s breadth of killing a man and did, in fact, cost the expedition a portion of its medicine, its powder, and its margin of supply at the threshold of the Continental Divide.
