Tips for Hiking Wall Street Mill

Start Early: Beat the crowds and enjoy cooler temperatures by starting your hike early in the morning, especially during peak season.

Bring Plenty of Water & Snacks: Carry plenty of water to stay hydrated, especially in the summer. Also, bring high-energy snacks to refuel and help maintain your energy during the hike.

Footwear and Gear: Some sections of this trail can be rocky, so wear comfortable, sturdy hiking shoes (or boots). Make sure you wear proper clothing for the season and bring layers just in case.

False Trails: Hiking trails within Joshua Tree National Park can be confusing due to difficulty following the trail markers (or lack thereof). I highly recommend downloading offline maps and having a physical map and compass in your backpack just in case you get off trail.

Leave No Trace: Stay on the trail, pack out all trash, and avoid picking plants or disturbing wildlife. Help keep Joshua Tree pristine for future hikers.

Summer Safety Tips:

Be sure to bring plenty of water to stay hydrated.
Eat high-carb and salty snacks to help keep your energy levels up and replenish electrolytes.
Wear lightweight, breathable clothing, a wide-brimmed hat, and sunscreen to protect yourself from the sun.
Try to hike during the cooler parts of the day, such as early morning or late afternoon.
Take frequent breaks in shaded areas.

History of Wall Street Mill

Before we explore the rich history of the Wall Street Mill, it’s important to acknowledge the deep cultural significance of this land. For centuries, the area was home to Native American tribes who relied on the natural rock shelters and abundant food sources for survival.

In the late 1800s, a man named William McHaney dug a well in the area, unknowingly setting the stage for a new chapter in its history. The well quickly became a vital watering hole for cattle, attracting settlers and shaping the land’s future as it transitioned from its indigenous roots to the mining boom that followed.

In the early 1900s, this area underwent a dramatic transformation – the discovery of gold! The desert landscape became the object of intense fascination as prospectors flooded in, eager to strike it rich. In 1928, Oran Booth and Earle McInnes staked their claim on the well site and established a homestead, naming it Wall Street to reflect the booming gold rush spirit of the time.

After a few years, Booth and McInnes left the site to seek new opportunities. In 1930, William Keys swooped in and claimed this area as a milling site. He built a bunk house and outhouse, and also transported a two-stamp mill ore crusher to the new site.

The mill soon became known as the Wall Street Mill. It was used to process ore extracted from nearby mines, including the renowned Desert Queen Mine. The ore was crushed and sifted in the mill to extract the precious gold hidden within. William Keys operated the mill for several decades, running it until around 1966. Wall Street Mill was eventually added to the National Register of Historic Places, preserving its legacy for generations to come.

Oh, I guess I should mention that William Keys was also a murderer. Continue reading to learn more about that tea. 😉

Another intriguing site along the Wall Street Mill Trail is the Wonderland Ranch. The Ohlson family established a homestead here, but little is known about them. It is believed that they were drawn to the area by the promise of gold mining opportunities. The remnants of their homestead still stand adding another layer of history to your hike.

Trail Directions

Barker Dam Parking Lot

Starting from the Barker Dam Parking Lot, head right and follow the trail signs towards Wall Street Mill. This parking lot also shares the trailhead for Barker Dam (hence the name of the parking lot).

Wonderland Ranch

Soon in the hike, you may or may not notice another trail veering off to the left. Take a short side quest to reach a place called Wonderland Ranch. Explore the ruins of this old homestead then head back to the main trail.

Old Cars & Gravestone

As you continue along the Wall Street Mill Trail, you will soon see an old wind mill at the Desert Queen Well. This well was used to support the operations of the Desert Queen Mine as well as livestock.

Along the way you will see various old rusty cars from the early 1900s. Amazing, right!?

The next piece of history you will see as you continue hiking is a (replica) gravestone. It reads, “Here is where Worth Bagley bit the dust at the hands of W.F.Keys. May 11, 1943.”

The backstory behind this memorial is that William Keys had a property dispute with a guy named Worth Bagley. Long story short, Keys shot Bagley and killed him. Keys was convicted of murder and sent to San Quentin Prison. He was released after five years due to the judge ruling that Bagley was killed in self-defense. Keys returned to his home and created a memorial for Worth Bagley.
