Most people think the American West ended when the census bureau said the frontier was closed in 1890. They’re wrong. The "Wild West" didn't just vanish because a government official signed a piece of paper. It bled out slowly, right into the era of Ford Model Ts and silent films. If you want to see the moment the old world finally collided with the new one, you have to look at 1918. Specifically, you have to look at a remote canyon in Arizona. This is where the last gunfight of the Old West—the Power Garden Canyon Shootout—went down.
It wasn't a noble duel. It wasn't O.K. Corral. It was a messy, tragic disaster involving draft dodgers, a gold mine, and a posse that didn't know what they were getting into.
Why the Power Garden Shootout Is the True Last Gunfight
History is rarely clean. Usually, when we talk about the last gunfight, people argue over technicalities. Does a police shootout in 1930 count? Not really. To be a "Western" gunfight, it needs that specific DNA: horses, lever-action rifles, and a complete lack of modern communication.
The Power brothers—John and Tom—along with their father Jeff and a friend named Tom Sisson, were living in the Galiuro Mountains. They were miners. Hard men. They weren't looking for trouble until the U.S. entered World War I. The brothers didn't register for the draft. Why? Some say they were pacifists, others say they just didn't think the government had any business telling them what to do in their own canyon.
Whatever the reason, the law came for them.
On February 10, 1918, a four-man posse rode up to their cabin. It was cold. It was early. The sun hadn't even fully cleared the ridges yet. Sheriff Robert McBride, Deputy Martin Kempton, and Deputy Kane Wootan expected a quick arrest. They didn't get one.

Tom Power later claimed he saw a man with a gun and reached for his own. The posse claimed the Powers fired first. Honestly, does it matter who pulled the trigger first when the result is a pile of bodies? In the frantic exchange of lead, three lawmen were killed. Jeff Power, the father, was shot while standing in the doorway holding a rifle—though his sons claimed he was trying to surrender.
He died in the dirt.
The brothers and Sisson didn't stay to talk it out. They grabbed their gear and vanished into the mountains. What followed was the biggest manhunt in Arizona history. It lasted weeks. This wasn't a high-speed chase. It was a slow, grueling crawl through some of the most unforgiving terrain in North America. They rode horses until the horses gave out. Then they walked. They crossed the border into Mexico, thinking they were safe.
They weren't.
They were eventually captured by the U.S. Cavalry. Think about that for a second. The last gunfight involved the actual cavalry. It’s a weird bridge between the 19th century and the modern world.
Debunking the Myths of the Power Brothers
You’ll hear a lot of romanticized nonsense about this event. Some people try to paint the Powers as Robin Hood figures. They weren't. They were scared, stubborn men who made a series of terrible decisions. But they weren't cold-blooded killers looking for a score either. They were caught in the gears of a changing country that no longer had room for "mountain men."

- Myth 1: They were German spies. (Total fabrication used to rile up the public during WWI).
- Myth 2: They had a secret gold stash. (They were broke; the "mine" was barely producing).
- Myth 3: It was a fair fight. (It was an ambush that turned into a massacre).
The trial was a circus. The brothers were sentenced to life in prison. Interestingly, they were eventually paroled in 1960. Think about that timeline. These men saw the end of the frontier, lived through two World Wars from a prison cell, and walked out into the age of television and space travel. Tom Power actually lived long enough to see a movie made about his own life.
The Cultural Weight of the Last Gunfight
Why do we care about a shootout in 1918?
It's because it represents the "closing of the door." When the Power brothers surrendered, the idea of the "untracked West" died with their freedom. You couldn't just hide in a canyon anymore. The federal government's reach had finally extended to every jagged peak and dusty wash in the country.
The last gunfight wasn't just about the bullets. It was about the law finally catching up to the land.
If you go to the Galiuro Mountains today, the cabin is still there. It’s a haunting place. Bullet holes are still visible in the wood. It serves as a grim reminder that the transition from the old world to the new wasn't a smooth evolution. It was violent. It was loud.
The Aftermath and Legal Precedents
The Power case actually highlighted some massive flaws in how the "posse comitatus" worked in the early 20th century. The deputies weren't highly trained tactical officers. They were locals with badges and a sense of duty. After this disaster, the way law enforcement handled mountain fugitives changed. It had to. You couldn't just ride up to a cabin and start yelling commands anymore without expecting a tragedy.

The legal defense for the brothers also sparked conversations about "duty to retreat." Did they have a right to defend their home if the lawmen didn't properly identify themselves? Even in 1918, the courts were struggling with the balance between individual liberty and state authority.
How to Explore This History Today
If you’re a history buff, you can actually visit these sites. It’s not a tourist trap. It’s rugged.
- Visit the Power Cabin: It's located in the Galiuro Wilderness. Warning: This is not a casual stroll. You need a 4WD vehicle and some serious hiking boots.
- The Safford Courthouse: This is where the trial happened. The atmosphere of the town still carries that heavy, desert-frontier weight.
- The Graves: You can find the graves of the fallen lawmen in the Safford and Thatcher areas. It puts a human face on the tragedy.
The last gunfight reminds us that history isn't just a series of dates in a textbook. It's people. It's mistakes. It's the sound of a Winchester rifle echoing off canyon walls while the rest of the world was busy inventing the future.
Actionable Insights for History Enthusiasts
If you want to dive deeper into the reality of the frontier’s end, stop looking at Hollywood. Start looking at local archives.
- Check Local Newspapers: Use sites like Chronicling America to look up February 1918 issues of Arizona papers. The "yellow journalism" of the time is fascinating and shows how the public was manipulated against the Powers.
- Understand the Geography: Open a topographic map of the Galiuro Mountains. When you see the elevation changes, you realize how insane the 25-day flight to Mexico actually was.
- Read "The Power Brothers" by Thomas J. Power: If you can find a copy, it’s Tom’s own account. It’s biased, sure, but it’s a primary source that gives you the "human" side of the fugitive experience.
The frontier didn't end with a sunset. It ended with a trial, a prison sentence, and a long, quiet silence in a remote Arizona canyon. We call it the last gunfight because, after 1918, there were no more places left to hide. The West was won, fenced, and filed away.
