Introduction
The Tillamook — rendered “Killamucks” or “Kil-a-mox” by the captains — were the Salish-speaking coastal people whose territory lay along the Pacific shore south of Point Adams, in present-day northwestern Oregon. During the four months the Corps of Discovery wintered at Fort Clatsop (December 1805 – March 1806), the Tillamook were among their most important trading neighbors, second only to the closer Clatsops and Chinooks. The journal record portrays them principally through Lewis’s ethnographic notebook entries and through the logistical drama of the salt camp and the beached whale.
First Contact and the Salt Camp
The expedition’s sustained contact with the Tillamook began with the establishment of the salt-making camp on the coast roughly fifteen miles southwest of Fort Clatsop. Lewis recorded on January 5, 1806 the return of Willard and Wiser, who had located the saltmakers near a Tillamook village:
they had at length established themselves on the coast about 15 Miles S. W. from this, near the lodge of some Killamuck families; that the Indians were very friendly and had given them a considerable quantity of the blubber of a whale which perished on the coast some distance S. E. of them.
This first impression — of friendliness and generosity with whale blubber — set the tone for much of the subsequent relationship. The blubber, Lewis reported, was “white & not unlike the fat of Poark, tho the texture was more spongey,” and “very pallitable and tender.”
The Beached Whale at Ecola Creek
The Tillamook’s most famous appearance in the expedition record concerns the whale that washed ashore in their territory. The summary entry of January 6, 1806 describes Clark’s organized party crossing Tillamook Head to Ecola Creek, where the whale’s skeleton — about 105 feet long — lay on the beach. It was here that Sacagawea made her well-known protest:
She observed that She had traveled a long way with us to See the great waters, and that now that monstrous fish was also to be Seen, She thought it very hard that She Should not be permitted to See either.
From the Tillamook the party purchased about 300 pounds of blubber and several gallons of oil — a meaningful supplement to the monotonous fort diet of elk and fish. Lewis later noted (January 25, 1806) that when other hunting failed, the saltmakers themselves “had been obliged to subsist on some whale which they procured from the natives.”
Place in the Coastal Trade Network
Lewis recognized the Tillamook as a node in a regional barter economy. On January 11, 1806, after the Cathlamet chief Shahharwarcap and his party departed Fort Clatsop, Lewis observed:
the Cuthlahmahs left us this evening on their way to the Catsops, to whom they purpose bartering their wappetoe for the blubber and oil of the whale, which the latter purchased for beads &c. from the Killamucks; in this manner there is a trade contin[ued]
Wapato roots from the Columbia Valley moved downriver; whale products moved up the coast and inland. The Tillamook stood at the seaward end of this exchange. In Lewis’s general trade summary of January 13, 1806, he listed the Tillamook (“those of the sea coast S. E. of the entrance of the river”) among the first of the nations who repaired to the trading anchorage inside Cape Disappointment when European vessels arrived between April and October.
Slavery and Captives
One of the more sober journal entries concerning the Tillamook touches on captive-taking. On March 1, 1806, Lewis described a boy in the household of a visitor named Kuskelar:
he had a good looking boy of about 10 years of age with him who he informed us was his slave. this boy had been taken prisoner by the Killamucks from some nation on the Coast to the S. East of them at a great distance. like other Indian nations they adopt their slaves in their families and treat them very much as their own children.
This is one of the few specific glimpses the journals offer into the Tillamook’s reach southward along the Oregon coast and their participation in the broader Northwest Coast practice of captive-taking.
Material Culture and Subsistence
Lewis’s ethnographic notebook entries treat the Tillamook as essentially of a piece with their immediate neighbors. On March 19, 1806 he wrote:
The Killamucks, Clatsops, Chinnooks, Cathlahmahs and Wac-ki-a-cums resemble each other as well in their persons and dress as in their habits and manners.
He described shared physical features — “thick broad flat feet, thick ankles, crooked legs wide mouths thick lips” — and a copper-brown complexion typical of the region. The remarkable canoes Lewis admired in his entry of February 1, 1806, capable of “riding high waves” with apparent ease, were the common property of these coastal nations.
Specific to Tillamook subsistence, Lewis noted on January 23, 1806 a particular bulb root:
this root is reather insipid in point of flavour, it grows in greatest abundance along the sea coast in the sandy grounds and is most used by the Killamucks and those inhabiting the coast.
Visitors at the Fort
Tillamook individuals occasionally appeared at Fort Clatsop itself, usually in mixed parties with Clatsops. On March 22, 1806, on the eve of departure, Lewis recorded:
about 10 A.M. we were visited by 4 Clatsops and a killamucks; they brought some dried Anchoveis and a dog for sale which we purchased.
This pattern — Tillamook traders arriving in small numbers, often as members of larger Clatsop or Chinook groups — suggests that the heart of expedition–Tillamook contact remained at the salt camp on the coast rather than at the fort.
Geographic Notes
As the Corps moved back up the Columbia in the spring, the Tillamook continued to figure as a geographical reference point. On March 29, 1806, Lewis described an inlet that “receives the waters of a small creek which heads with killamucks river” — placing the Tillamook drainage in his evolving mental map of the Columbia–coast watershed. The earlier entry of January 10, 1806, recording the visit of the Cathlamet chief, had similarly used the Tillamook as a fixed point in describing the linguistic and cultural geography of the lower river.
Limits of the Record
Although the journals mention the Tillamook in fifteen entries, the depth of personal contact recorded is shallower than with the Clatsops or Chinooks. No Tillamook leader is named in the way Comowooll (Clatsop) or Delashelwilt (Chinook) is named. Most observations come filtered through the saltmakers’ reports or generalized into Lewis’s pan-coastal ethnography of March 19. The Corps stayed near, traded with, and ate the food of the Tillamook for an entire winter — but the journal record preserves their presence largely as friendly suppliers of whale blubber, sandy-shore root foods, and a steady backdrop to the salt camp’s labors.
Conclusion
The Tillamook emerge from the journals as essential, if somewhat anonymous, partners of the Fort Clatsop winter. They fed the saltmakers when game failed, supplied the blubber and oil that broke the monotony of expedition fare, anchored the southern end of a coastal trade in whale products, and provided Lewis with much of the comparative material for his ethnography of the lower Columbia peoples. That the Corps survived the winter in tolerable health owes something to the friendliness Lewis remarked upon at the very first mention of them on January 5, 1806.
