The arrival at Tumwater of the first American colony on Puget Sound, October 1845
The Story
In October 1845, the first party of American settlers reached the falls at Tumwater, at the southern tip of Puget Sound, and put down roots in country still claimed jointly by Britain and the United States. Led by Michael Simmons and including the free Black pioneer George Bush, the group founded the earliest American colony north of the Columbia River. Their settlement helped tip the balance in the coming boundary dispute.
Why it matters
This foothold on Puget Sound anchored the American claim to the Pacific Northwest, just before the 1846 treaty fixed the border at the 49th parallel.
The story behind this marker
AI contextThe era
In the mid-1840s, the far northwest corner of the continent was a place of divided loyalties on the map. The land around Puget Sound lay within the Oregon Country, a vast region that Britain and the United States had agreed to occupy jointly rather than fight over. British fur-trading interests dominated the ground, and few American settlers had pushed north of the Columbia River.
That river was the unofficial line. American wagon trains coming west tended to settle in the fertile Willamette Valley to the south, leaving the country around Puget Sound largely to Native peoples and the British-aligned traders. To plant an American farming community at the very foot of the Sound, in October 1845, was to step deliberately across that line.
The falls at Tumwater, where a river drops toward the salt water at the southern tip of the Sound, offered exactly what a young settlement needed: waterpower to run a mill, timber all around, and access to the sea. It was a practical place to stop, and a pointed place to stop.
People & events
The party that arrived here in the autumn of 1845 is remembered as the first American colony on Puget Sound. It was led by Michael Simmons, and among its members was George Bush, a free Black pioneer whose presence gives the story a particular weight. Bush had reportedly prospered on the trail and helped hold the group together, yet the laws taking shape in the Oregon Country were increasingly hostile to Black settlers — one reason a party including him may have looked north of the Columbia for a place to put down roots.
What they did was ordinary and monumental at once. They chose ground, built shelter, harnessed the falls, and began the slow labor of turning a wilderness landing into a working settlement. Every cabin raised and every furrow turned was also, whether the settlers thought of it that way or not, an argument about who would ultimately hold this country.
The marker fixes the moment precisely: the arrival, at Tumwater, in October 1845. It is the founding date of American settlement on the Sound, and the beginning of a community whose descendants and successors would fill in the map around it.
Its place in the American story
This small colony landed at a decisive hinge in the story of the American West. Within months of these settlers arriving, the long dispute over the Oregon Country came to a head, and in 1846 a treaty fixed the boundary between British and American territory at the 49th parallel — bringing Puget Sound firmly onto the American side.
Diplomacy settled the line, but facts on the ground shaped the diplomacy. Every American family living and farming north of the Columbia strengthened the case that this was, in practice, American country. A colony at the foot of the Sound was worth more to that argument than any speech.
There is a second thread here that reaches into the national story: the presence of George Bush among the founders. His journey west, in the face of laws designed to exclude people like him, is a reminder that the settlement of the Pacific Northwest was carried out by a more varied cast of Americans than the simple frontier myth allows.
If you visit
Come to Tumwater and let the setting do the explaining. The falls are still the heart of the place — moving water dropping toward the salt water of the Sound, the same power that first drew settlers to stop here rather than press on. Standing near them, it's easy to understand why a founding party chose this exact spot.
The marker is compact and understated, the kind you read in a minute and then think about for longer. Use it as a prompt to look around at how far the modern town has grown from that first small landing, and to picture the country as it was when this was the northernmost edge of American settlement.
It slots naturally into any exploration of the south Sound and the Olympia area. Give a few minutes to the water and the view, and to the improbable image of a handful of families — one of them led across the continent with a free Black pioneer among them — betting that this shore would end up American.

Site of Wilkes Observatory
DuPont, WA
Built in 1841, this building housed observations made during the United States Exploring Expedition, the great naval and scientific survey led by Lieutenant Charles Wilkes. The expedition charted Pacific coasts and islands and gathered specimens that helped seed the young nation's scientific institutions. A later marker from the DuPont company recalls the work once done on this ground.
First Pierce County Courthouse
Steilacoom, WA
When this courthouse rose in 1859, Washington was still a raw territory two years from statehood conversations and decades from becoming a state. Pierce County was organizing its civic life on the Puget Sound frontier, and a permanent courthouse signaled that law, records, and local government had taken root in Steilacoom, one of the territory's earliest American towns. The building served for over seventy years before it was razed in 1932, and pioneer descendants set this marker in 1962 to keep its footprint remembered.

This marker recalls a military road cut through the Puget Sound country that, during the Indian War of 1855, offered settlers in the Puyallup Valley their only escape route to the shelter of Fort Steilacoom. Along the same corridor in 1864, crews strung the Russian-American (Collins Overland) Telegraph Line, an audacious scheme to link America to Europe by wire across Alaska and Siberia.
