The record — long form
The Yuma Territorial Prison was the hole in the ground where the territory put its worst — the granite bluff over the Colorado where the cells were dug into the rock and the dark cell was a cage inside a cave with no window and a ceiling too low to stand. The first seven inmates moved in July 1876; the prison held three thousand over its thirty-three years, in the place the prisoners called the Hell Hole and the promotional materials called the Country Club on the Colorado. Both were true — the prison had electricity and a library and sanitation, and the dark cell was a five-foot cage in a cave.
The inmates built their own prison — the labor that dug the cells and set the walls was convict labor, the men who were sentenced to Yuma building the place that held them. Pearl Hart served time there — the stagecoach robber who became the prison's most famous female inmate. The Mormon polygamists convicted under the anti-polygamy laws were the prison's political prisoners — the men the federal government locked up for their marriages, in the cells the territorial legislature had appropriated twenty-five thousand dollars to dig.
The prison closed in 1909 when the inmates were moved to Florence; the buildings stood on the bluff through the Depression, used as a school and picked over for materials, until the 1930s restoration made it a museum. The cells are still there — the narrow four-by-eight cubicles, the iron cage in the dark cell's cave, the guard tower over the river the prisoners could see and not reach.
Yuma is the archive's hell-hole file — the prison that was the territory's answer to its criminals, the dark cell that was a cage inside a cave, the place that was progressive and brutal in the same walls on the bluff over the Colorado.
Why this file matters
Yuma Territorial Prison is the archive's desert file — the prison dug into the granite bluff where the inmates built their own cells, the dark cell that was a cage in a cave, the Hell Hole that was also the territory's most modern facility for thirty-three years.
A prison in a cave keeps its dark cell — the file's suggestion being that Yuma's haunting is the hole itself: the five-foot cage in the granite where the worst punishment was the darkness, in the prison that held three thousand on the river they could see from the tower.
