A Valley of Heat and Cold: Five Views of the Upper Jefferson

5 primary source entries

The Same March, Five Registers

The party ascended the Jefferson on August 2, 1805, through a broad valley flanked by parallel mountain ranges still patched with snow. All five journalists agree on the basic facts: an early start, a warm day, a shallow and rapid river, abundant beaver sign, and a camp on the south or larboard bank. But the distance recorded varies sharply. Lewis and Gass both log roughly 24 miles; Clark estimates only 15; Ordway writes 14¼ and Whitehouse 14¾. The discrepancy likely reflects which detachment each man traveled with—Lewis was on shore ahead of the canoes, while Clark, hobbled by a swelling ankle, stayed with the boats fighting the current.

Lewis alone records the day’s most consequential maneuver: a deliberate fording of the river to shorten the route.

finding that the river still boar to the south I determined to pass it if possible to shorten our rout this we effected about five miles above our camp of last evening by wading it. found the current very rappid about 90 yards wide and waist deep this is the first time that I ever dared to make the attempt to wade the river

None of the other four mention the crossing, confirming that Lewis was traveling with the overland party while the canoes worked the channel separately. Gass, who appears to have been with Lewis, notes the crossing in a single clause—”proceeded 4 or 5 miles and crossed the river”—but adds nothing about its difficulty or significance.

Ordway and Whitehouse: The Documented Echo

The Ordway-Whitehouse parallel is unusually tight on this date. Compare the openings: Ordway writes “The River is now Small crooked Shallow and rapid, passed bottoms covered with cotton Timber.” Whitehouse writes “the River is now Small crooked Shallow and rapid. passed bottoms of cotton timber.” The sequence of observations—beaver sign, the bank-swallow village, the old Indian camps, the two grey eagles, the gang of elk “back under the hills,” the closing remark that “the country in general back from the river is broken and mountaineous”—appears in nearly identical order in both journals. Whitehouse adds one personal note Ordway lacks: “I have a pain in my Shoulder.” He also specifies that the eagles “had nests on the top of dry trees,” a detail Ordway omits. The pattern fits the established understanding that Whitehouse drew heavily on Ordway’s field notes while inserting his own physical complaints and minor elaborations.

What Each Narrator Alone Preserves

Lewis devotes nearly half his entry to botany. He catalogues currants in four colors—red, yellow, “deep purple and black”—alongside ripe black gooseberries and serviceberries, comparing the currant to the garden variety “common to the gardens in the atlantic states” and pronouncing the purple serviceberry “excellent.” No other journalist mentions fruit at all. Lewis also closes with a note on his own health: “I feel myself perfectly recovered of my indisposition.”

Clark, by contrast, opens his health ledger just as Lewis closes his:

I have either got my foot bitten by Some poisonous insect or a turner is riseing on the inner bone of my ankle which is painfull

This is the first appearance of the ankle abscess that will plague Clark for days. He alone notes rattlesnakes “in the plain” that morning, and he alone identifies the black woodpeckers (Lewis’s woodpecker, Picoides arcticus or possibly Lewis’s woodpecker proper) among the day’s birdlife.

Gass contributes the day’s sharpest weather contrast in two lines: “In the middle of the day it was very warm in the valley, and at night very cold; so much so that two blankets were scarce a sufficient covering.” Lewis records the same observation almost verbatim—”the nights are so could that two blankets are not more than sufficient covering”—suggesting either shared conversation in camp or Gass’s familiar habit of compressing Lewis.

The Composite Day

Read together, the five entries reconstruct a day no single journal captures: Lewis fording the river ahead and grazing on serviceberries; Clark limping in the canoes past rattlesnakes and woodpeckers; Gass marching with the shore party and feeling the temperature swing; Ordway logging the beaver dams “one dam above another which is curious to behold”; and Whitehouse copying Ordway while nursing a sore shoulder. The valley is narrowing, the river shrinking toward its sources, and the men are beginning to register their bodies as carefully as the landscape.
