Lewis and Clark on the Yellowstone
Park City, Stillwater County, Montana
Marker Inscription
This plague, located just in front of the Park City Kwik Stop, tells the story of the site where William Clark and some of the other members of the Corps of Discovery stopped on the Yellowstone River, near Park City, to build canoes.
The Story
Near this spot on the Yellowstone River in July 1806, William Clark and part of the Corps of Discovery paused during the expedition's homeward journey to fell cottonwoods and build dugout canoes for the trip downriver. Clark's party had split from Meriwether Lewis to explore the Yellowstone, and their passage through this valley was among the first documented American ventures into what is now south-central Montana.
Why it matters
It marks a tangible point along the Lewis and Clark expedition, the epic reconnaissance that opened the American West to the young United States.
The story behind this marker
AI contextThe era
In the summer of 1806, the valley of the Yellowstone River in what is now south-central Montana was open, unmapped country from the perspective of the young United States. Just three years earlier, the Louisiana Purchase had roughly doubled the size of the nation on paper, and the government had sent an expedition west to see what it had bought and to find a way across the continent.
That expedition, the Corps of Discovery, was on its long journey home by the time it reached this stretch of the Yellowstone. The outbound leg had already carried the party to the Pacific; now the challenge was to return, gathering as much knowledge of the land, its rivers, and its peoples as possible along the way.
This was the Early Republic reaching westward — a country barely a generation old, testing the limits of its new territory. The Yellowstone valley, rich in game and threaded by a great navigable river, was exactly the kind of country the expedition had been sent to understand.
People & events
The marker centers on William Clark, who led part of the Corps of Discovery through this valley. On the homeward journey, the expedition had divided: Clark took a group to explore the Yellowstone while Meriwether Lewis followed a separate route, the better to learn as much of the country as they could before reuniting downstream.
Here, near Park City, Clark's party paused for a very practical reason — they needed boats. The marker recalls this as the site where Clark and members of the Corps stopped to build canoes, felling cottonwood trees along the river and shaping them into dugouts sturdy enough to carry the party down the Yellowstone.
It's a humble, human moment in an epic journey: not a battle or a grand discovery, but the hard, ordinary work of making watercraft from the trees at hand. That labor was what made the rest of the river voyage possible, and it left this quiet valley with a genuine claim on one of the great stories of American exploration.
Its place in the American story
The Lewis and Clark expedition is one of the founding adventures of the American nation — the reconnaissance that opened the vast western territory to the understanding, and eventually the ambitions, of the United States. Every documented stop along its route is a thread in that larger story.
Clark's passage down the Yellowstone was among the first documented American ventures into this part of the West. The maps, observations, and encounters recorded on such journeys transformed a region known intimately by its Native inhabitants but blank to the young republic into country the United States would soon push to claim and settle.
A marker at a canoe-building site connects a specific patch of Montana ground to that continental drama. It reminds travelers that the westward expansion which so shaped the nation did not happen in the abstract — it happened riverbend by riverbend, in valleys like this one, through the daily efforts of the people who made the journey.
If you visit
The charm of this stop is its unassuming setting — the plaque stands near an everyday roadside spot in Park City, which makes the history it tells feel all the more surprising and close at hand. Pause and read it, then let your eyes go to the river.
The Yellowstone is the real monument here. Look for the cottonwoods along its banks, the very kind of tree Clark's party would have felled and hollowed into canoes. Picture the work of it: the felling, the shaping, the launching of rough dugouts onto the current for the long trip downriver.
For anyone traveling through south-central Montana, this makes a rewarding quick stop that links the landscape to a national epic. Stand by the water, imagine the Corps of Discovery at their labor, and you've touched a real and tangible point on one of the most famous journeys in American history.

John Mullan Trail Marker
Fort Benton, MT
This marker follows the path of the Mullan Trail, the military wagon road that Captain John Mullan and his crews surveyed and cut between 1853 and 1855 as part of the larger effort to connect Fort Benton, Montana, at the head of Missouri River navigation, with Fort Walla Walla in Washington Territory. Built through rugged mountain country, it opened the first wheeled route across the northern Rockies and funneled soldiers, settlers, and miners into the region.
Fort Benton National Historic Landmark
Fort Benton, MT
This plaque recognizes Fort Benton as a National Historic Landmark under the Historic Sites Act of 1935, affirming its exceptional value to American history. Founded in the 1840s as a fur-trading post on the upper Missouri River, Fort Benton became the innermost port reachable by steamboat—the "head of navigation"—and a bustling gateway for freight, gold seekers, and settlers bound for the northern Rockies. From here the Mullan Road and trails fanned out into Montana and the Pacific Northwest.
Chief Joseph
Ryegate, MT
On September 17, 1877, Chief Joseph and the Nez Perce (Nimiipuu) forded the Musselshell River here during their extraordinary fighting retreat toward Canada. Driven from their homeland in Idaho's Wallowa country after refusing to cede it, hundreds of men, women, and children traveled more than a thousand miles pursued by the U.S. Army, only to be halted just short of the border.
Capt. John Mullan
Missoula, MT
Captain John Mullan is best remembered for the military wagon road he engineered across the northern Rockies, but this marker recalls his earlier trail-work of 1853–1855, when he explored and surveyed routes through the mountains of the Northwest. His efforts helped open a practical overland path between the Missouri and Columbia river systems. The roads that followed carried soldiers, settlers, miners, and freight into a remote corner of the country.
