Poston camp preserves rare Japanese American history on tribal land

Poston’s next chapter is being built around one surviving barrack in Parker and the buildings that still stand at Poston Camp 1. The Poston Community Alliance is working to move that barrack back to the original camp site and restore it there, using federal preservation support to make the history easier to see, walk, and teach on Colorado River Indian Tribal land.

What is being rebuilt at Poston

The immediate restoration focus is a barrack currently at a nursery in Parker, which the Poston Community Alliance plans to relocate back to Poston Camp 1. The group says the goal is not just preservation for its own sake, but a living museum and interpretive center that can explain how the camp functioned and why the place matters to Japanese American and Native American history.

That matters because Poston is not a blank archaeological field. It is one of the few surviving places where visitors can still connect physical structures to the wartime confinement story. The alliance’s work is aimed at making the site more legible, especially for people who know the name Poston but have not yet seen how much of the school complex and surrounding camp landscape remain.

Why Poston I carries the story

Poston opened on May 8, 1942, beginning with the arrival of 11 Japanese-American volunteers. It was organized into three units, Poston I, Poston II, and Poston III, and at its peak it held 17,814 people. That made it Arizona’s third largest city at the time, a scale that is hard to grasp today unless you stand on the land and trace how the camp was laid out.

The most visible remains today are concentrated at Poston I. The elementary school’s adobe auditorium and nearby school buildings are still standing, and the elementary school complex is the key reason this unit has become the center of preservation planning. Poston I is also the only relocation center site with a separate school complex, and Poston Elementary School, Unit I, is recognized as a National Historic Landmark.

Poston II and Poston III tell a different story. At Poston II, the most visible remains are the sewage treatment plant remains, while Poston III is marked mainly by the sewage treatment plant. Those remnants are far less legible to the public than the school buildings at Poston I, which is why the current restoration effort is focused where visitors can actually understand the camp’s scale and daily life.

A site on tribal land, not just county land

Poston sits about 12 miles south of Parker, roughly 110 miles west of Phoenix on the Arizona-California border. The wartime camp was built on the land of the Colorado River Indian Reservation, making it the only relocation center located within an American Indian reservation. During World War II, the area was part of Yuma County, not La Paz County, which gives the site an unusual local history: the camp is now central to La Paz County identity even though the county did not yet exist when the camp operated.

That layered geography is one reason the site matters now to residents, descendants, and educators. Poston brings together Japanese American incarceration history, tribal land history, and the history of this stretch of the lower Colorado River in one place. The camp was named for Charles DeBrille Poston, the first Superintendent for Indian Affairs in Arizona and the man responsible for establishing the Colorado River Reservation in 1865, which adds another historical thread to the site’s meaning.

What visitors can see now

Poston already has some public interpretation on site. The monument at Poston I was dedicated in 1992, and the kiosk followed in 1995. Both include interpretive signs that discuss relocation history, Japanese American military service, and the Colorado River Indian Tribe. Those markers make the place readable for first-time visitors, but they do not fully explain the scale of what happened there or how the camp’s surviving buildings fit together.

The new preservation work is meant to change that. Restoring the barrack at Poston Camp 1 would give visitors a more immediate sense of how the camp looked and how tightly the school, living quarters, and service structures were connected. For teachers and students in La Paz County, that means the site can function less like a distant memorial and more like a place where local history is visible in the land itself.

The organizations driving the work

The Poston Community Alliance has been central to the preservation effort. It became a 501(c)(3) nonprofit in 2007, and its preservation history says the Colorado River Indian Tribal Council dedicated 40 acres for historic preservation of Poston Camp I. That land dedication gives the project a concrete footprint and shows that the preservation work is not symbolic alone.

The alliance’s public mission is to preserve Poston’s incarceration history in support of social justice and to keep alive the multicultural story of Japanese Americans and Native Americans at the site. Its presentations have included Dennis Patch, a former Colorado River Indian Tribe tribal chairman; Marlene Shigekawa, the alliance president; and Valerie Welsh-Tahbo, the CRIT Museum Director. Mich Himaka, the tribe’s tribal historic preservation officer, is also named as a stakeholder in the preservation conversation.

Shigekawa has also organized Poston pilgrimages since 2018, drawing more than 1,000 attendees. That kind of turnout shows there is already a live audience for the site’s history, not just an abstract interest in it. The planned barrack relocation and restoration build on that existing public attention.

Why the landscape still matters

Poston’s physical landscape still carries features built by people who were confined there. National Park Service records note that detainee-built irrigation infrastructure from the camp is still in use, a reminder that the camp altered the land in ways that outlasted the war years. The records also note that some buildings from the relocation center were later moved into the surrounding community for utility or other uses, which means the camp’s footprint was not simply abandoned when confinement ended.

That makes preservation at Poston different from restoring a single building in isolation. The school complex, the surviving remains at the other units, the monument and kiosk, the irrigation system, and the planned return of the barrack all point to the same conclusion: the site still has enough surviving fabric to teach how the camp functioned and why it remains significant on tribal land.

For La Paz County, the value is practical as well as historical. Poston is a place where the county’s present-day civic life, tribal history, and Japanese American memory meet in public view. The current restoration effort gives residents a clearer landmark, educators a stronger teaching site, and descendants a place where the story is not only remembered but physically kept in place.
