I hiked to an abandoned mining mill in the California desert that was the site of a shootout. Today, only ruins and rusty cars remain.

• I discovered much more along the path, including the site of a shootout, rusty cars, and ruins.

Otherworldly Cholla cacti and Joshua trees often lure visitors to the Joshua Tree National Park — but the 792,623-acre park has much more than odd fauna.

The park was once home to a scattering of mines. And on a recent visit, I embarked on a two-mile hike to discover the region's mining history, walking the Wall Street Mill trail.

Here's what I saw along the route.

I entered the west entrance of Joshua Tree National Park and headed for the Wall Street Mill hiking trail.

Arriving at the trail, as I looked along the horizon, I spotted plenty of Joshua trees but I didn’t see any abandoned structures.

So I set off in search of the Wall Street Mill.

As I kicked sand into my shoes and hiked along a marked path, I finally spotted something pink in the distance.

A short detour from the trail led to a handful of partially standing walls and what was once a fireplace. Together, they made up the Wonderland Ranch ruins.

According to Atlas Obscura, not much is known about the ruins. And the photography website Cali49 says the structures are thought to have once been home to the Ohlson family.

As I explored the site, not much remained beyond a fireplace, foundation, and crumbling walls.

Any bits of wood had been burned to a crisp, and the pink paint was chipping off the stone.

After exploring the site, I continued toward the mill.

Along the path were reminders of the area’s history.

For example, I saw an old windmill with a water pump and reservoir.

And after a mile on the sandy trail, I arrived at the Wall Street Mill.

The first thing I spotted was an abandoned truck.

All that remained was a skeleton of the former car. The rubber wheels had worn out in the hot sun, the engine no longer existed, and the fabric of the truck’s seats had disappeared.

Behind the truck was the old mill site.

A sign explained that these abandoned buildings and machinery were built during the Great Depression when a second gold rush occurred in the area.

And a local rancher named Bill Keys saw an opportunity. There was a need for a place to process the ore, so he decided to build a mill to do just that, according to the trailhead sign.

In 1930, Keys bought the land where the Wall Street Mill sits today. After acquiring the land, he built a bunkhouse, outhouse, and gathered machinery for the mill, as the same sign explains.

Miners at nearby mines would transport ore to the mill. That ore would then be crushed and processed, and the gold would be extracted.

Keys worked with smaller mining operations on an as-needed basis, according to the sign at the trailhead. The last time the Wall Street Mill was used was in 1966.

I spotted the mill’s old rail tracks, winch, and shed, which were surrounded by a fence protecting the site, which is now listed in the National Register of Historic Places.

After exploring the Wall Street Mill, I had one thing left to see: the Worth Bagley stone.

The stone marks the spot where Worth Bagley was killed by Keys.

Keys and Bagley were neighbors, and the pair had gotten into a property argument over water, a sign along the trail states.

On May 11, 1943, the argument turned fatal. A shootout took place between the neighbors, and Bagley was killed. Keys was convicted of murder and sent to prison.

In 1948, a judge pardoned Keys and ruled that the his actions were self defense. When Keys returned to the site, he marked the shootout location with a stone that reads: "Here is where Worth Bagley bit the dust at the hand of W.F. Keys."

Over the years, visitors have vandalized the stone. So today, a replica of the original remains in the spot.

I continued back toward my car, where I discovered more artifacts, ruins, and abandoned cars.

The short trail transported me back to a time when shootouts and mining for gold weren't just scenes in Western movies, and I left with a better idea of what life might have been like back then.
