The Original Franklin County Seat: A Ghost Town Called Ainsworth

Even during its booming heyday, a U.S. Army engineer first described Ainsworth, Washington, as a rough-and-tumble railroad town choking on sand and summer heat in the wildest part of the Wild West by saying it was “One of the most uncomfortable, abominable places in America to live in.” Between the brawls, gunfights, and acts of vigilante justice, the dust here never had a chance to settle. Still, despite it all, 8,000 fortune-seeking laborers would call it home, taking a gamble on a lawless frontier that in the end would fold, leaving behind nothing more than a ghost town.

Before the Boom: A Confluence of Rivers and History

Long before iron rails pierced through the sagebrush, the wind-swept plain at the confluence of the Snake and Columbia rivers was already historically significant. On October 16, 1805, the Lewis and Clark Expedition camped on this very spot, their first introduction to a windswept desert brought to life by two arterial waterways that had surprisingly sustained Native communities for generations. For thousands of years, Native Americans gathered at this meeting of the rivers to trade, fish, and maintain kinship ties between tribes.

Following the Nez Perce and Bannock Wars of the 1870s, developers across Eastern Washington saw an opportunity to push Native communities aside and lay claim to the land, clearing the way for ranches, towns, and agricultural industries to take root along the river valleys. Still, the sandy, sun-scorched flatland held little appeal to traditional homesteaders. There was no shade, no timber, and relentless winds blew blinding sand across the plains. It would take a grander industrial ambition, and the arrival of the railroad, to transform this quiet confluence into one of the wildest towns in Washington Territory.

The Northern Pacific Railroad Arrives: Ainsworth is Born

The transformation happened almost overnight in October 1879, when Northern Pacific Railroad surveyors descended on the north bank of the Snake River, laying stakes for a new major depot. The goal was to extend the Pend Oreille Division of the railway westward, ultimately connecting the region between Helena, Montana and the Pacific Coast via the Columbia River. Platted by U.S. Army Engineer Thomas Symons, the new settlement was named Ainsworth in honor of Captain John Commingers Ainsworth, a prominent Oregon businessman and president of the Oregon Steam Navigation Company.

Symons held no illusions about the hostile terrain he was mapping, famously recording that one could scan the horizon in vain for a single tree while summer heat and blinding sandstorms caused perpetual eye torment. Yet industrial progress superseded human discomfort, and the railroad moved forward without reservation, quickly erecting two massive desert sawmills to churn out railroad ties and construction timber. Steamboat Captain William Polk Gray established a lucrative river trade to fuel the operation, towing massive log booms downriver from forested ranges in Idaho, the Cascades, and the Blue Mountains. Within a matter of months, the desolate shore transformed into a packed, bustling railroad hub. The second sawmill, having been built a few short years later in 1881, was said to have at one time produced an estimated 65,000 to 80,000 feet of rough lumber per day.

Life in a Lawless Town: Ainsworth Puts the Wild in Wild West

By the early 1880s, Ainsworth had transformed into a sprawling, chaotic metropolis of construction, with thousands of laborers pouring into what had already earned a reputation as the rowdiest frontier town around. While historical estimates put Ainsworth’s permanent townsite population between 400 and 1,500 people, the surrounding transient workforce of rail crews, contractors, and timber hands pushed the local headcount closer to 8,000.

Up to half of this massive workforce consisted of Chinese immigrants. Over 5,000 Chinese laborers were recruited to work around the clock, laying track and cutting rail lines through the punishing terrain of the Columbia River Gorge. According to The Spokan Times in November 1879, white laborers received $1.50 per day (paying $4.50 per week for board), while teamsters earned between $3.50 and $5.00. Meanwhile, the Chinese workers, facing harsh conditions and low wages, often lodged in long strings of railcars configured as mobile bunkhouses. Within town, Chinese entrepreneurs established their own vibrant district, operating laundries, eateries, trade shops, and traditional medicine stores.

With that many people crammed into a desert outpost, order was hard to come by. Brawls and gunfights were daily occurrences, and with formal law enforcement largely absent, justice was regularly meted out by vigilantes at the end of a hangman’s rope. In addition, saloons, gambling halls, and reportedly even Chinese opium dens and houses of ill-repute lined the dusty streets, creating an atmosphere of constant chaos. It was as wild and woolly as any town the American frontier ever produced.

Peak Prominence: Ainsworth’s Moment as County Seat of Franklin County

Despite its rampant lawlessness and brutal environment, Ainsworth held immense political and economic sway in the region. Because it sat at the heart of the regional transportation trade and boasted the largest population in the area, the town reached its civic peak in late 1883.

On November 28, 1883, the Washington Territorial Legislature officially established Franklin County out of a portion of Whitman County. Recognizing its sheer size and economic momentum, lawmakers designated Ainsworth as the inaugural county seat for the newly formed 1,242-square-mile territory. For a brief moment, the rough-and-tumble rail camp was the official center of regional government.

From Boomtown to Ghost Town: The Bridge That Changed Everything

Ainsworth’s fortunes turned in 1884, when the Northern Pacific completed a railroad bridge across the Snake River. The 1,540-foot structure, which cost over $1.1 million to build, connected the Montana rail line to the Columbia River routes. The bridge was built less than a mile upstream from Ainsworth, connecting instead to a new small settlement called Pasco. Founded in large part by Captain Gray and his associates, Pasco was pitched as the calmer alternative to Ainsworth’s chaos. Within just a month of its founding, Pasco already had a hotel, two saloons, and three places to get a hot meal.

The shift proved swift and permanent. The Northern Pacific relocated its junction operations to the newly founded Pasco Junction, where they built housing for its employees and established a roundhouse. The local school followed soon after. By 1885, many of Ainsworth’s buildings had been either dismantled entirely or physically hauled to Pasco. The Chinese laborers who remained also relocated, establishing their own district in the new town, though most left altogether once the railroad work dried up. That same year, the Washington Territorial Legislature made it official, formally moving the Franklin County seat to Pasco, which was incorporated on September 3, 1891.

Once the buildings and people were gone, the desert began reclaiming what little remained. The sand and sagebrush that had always surrounded Ainsworth crept back in, and by the close of the 19th century, virtually no trace of the once-bustling town remained standing. In barely five years, Ainsworth had gone from a raucous boomtown of thousands to nothing more than a forgotten ghost town.

A Ghost Town Called Ainsworth: What’s Left Today

Today, the site of Ainsworth sits along the Snake River just north of Sacajawea State Park, perched on a knoll overlooking the park’s Confluence Story Circles near where the Snake and Columbia rivers meet. It’s a far cry from the barren, treeless plain that once housed thousands of workers, now replaced by the park’s 267 acres of trees, manicured lawns, and walking paths. Gravel and dirt roads along the park’s north side lead toward a brushy stretch of riverbank believed to mark the former townsite, though decades of flooding, a persistent problem until dams were built in the mid-20th century, have erased most physical evidence. A few old foundations and broken slabs of concrete can still be spotted, some even visible just offshore in the river itself, but it’s difficult to say for certain whether they’re remnants of the town or of a later ferry operation that ran through the area.

As Pasco grew up around the old townsite, and Kennewick and Richland rose nearby to complete what’s now the Tri-Cities, the land that once held one of the wildest, most populous towns in the territory was gradually engulfed and forgotten. In barely five years, Ainsworth had gone from a thriving boomtown of thousands to a solemn ghost town, its story surviving not in stone or steel, but in the silence of a place that had risen from nothing and returned to it just as quickly; ashes to ashes, dust to dust.
