The situation had been different a century earlier. Between Celilo Falls—above The Dalles—and the mouth of the Columbia, speakers of Chinookan dialects dotted the river islands and entry points of small rivers and streams. Their “metropolis” was Sauvie Island and the adjacent Oregon shore, a scant ten miles from the future fairgrounds. Lewis and Clark counted 2,400 people on the island and 1,800 along the south side of Multnomah Channel. Six years later, British fur trader Robert Stuart reported a population of about 2,000 on the island itself—a denser population than the island supports today. There were perhaps fifteen separate villages on Sauvie Island and immediately adjacent areas. Residents fished for salmon, sturgeon, and smelt; hunted migratory birds and deer; gathered nuts and berries; and dug wapato roots along the rivers. “Wappato Island” was Lewis and Clark’s name for Sauvie Island. Cedar logs provided materials for canoes, cooking utensils, and longhouses. Villages were built to last for years rather than decades, for the abundance of natural resources made it easy for a group to move from one spot to another within its general territory.

In contrast to their bustling settlements along the Columbia, Native Americans made only limited use of the lower Willamette River. Not until they reached the Clackamas River and the Willamette River falls, twenty-five miles upstream, did European explorers find more than scattered and often temporary settlements. Here, where the salmon stopped, the natural environment again made life relatively easy for the Cushook, Chahcowah, and Clackamas peoples. The falls were a point of contact between maritime groups and hunting peoples of the Tualatin Valley. Twenty or so small villages of Tualatin Indians used the valley, traded with river people, and occasionally gathered near Gaston. They were a subgroup of the Kalapuyas of the central Willamette Valley, all of whom had learned to improve their environment with periodic fires. Their purpose, they told naturalist David Douglas, was to clear the land for ease of gathering wild foods and to force deer into areas where they were easy to hunt.

The growing presence of white traders introduced a very different change in the natural environment that now destroyed the Native Americans whom it had nurtured. Among the world's most isolated peoples, the Indians of the Northwest Coast were easily susceptible to new diseases that arrived with Europeans. Smallpox came upriver in the 1770s, 1801-1802, and 1824-1825. In 1830, the “Cold Sick” or “Intermitting Fever” appeared in Chinook and Kalapuya villages. It raged for the next three years along the Willamette and lower Columbia. It is likely that the disease was malaria brought from the tropical Pacific by traders. Whatever its true identity, the Cold Sick spread outward from an infection epicenter at Sauvie Island and Fort Vancouver. It killed half in some villages, 90 percent in others, leaving a few hundred Native Americans and a virtually unoccupied Willamette Valley landscape for the English-speaking settlers who began to arrive over the Oregon Trail in the 1840s. By 1905, the few thousand survivors of plague and war were squeezed onto reservations east of the Cascades and scattered near the coast.
