Est. 1933 · Best-preserved gold ore stamp mill in Joshua Tree NP · Keys-Bagley 1943 homicide case · Earle Stanley Gardner legal intervention · Desert homesteader history
William F. Keys was among the most durable of Joshua Tree's desert homesteaders. He had already established the Keys Ranch (separately listed on the National Register of Historic Places) when he built the Wall Street Mill in 1933, hauling two-stamp milling machinery and supporting structures — a bunkhouse, well, and outhouse — from an abandoned site at Pinon Wells to Queen Valley to process gold ore from the area's small mines.
By the late 1930s Keys was in a sustained dispute with his neighbor Worth Bagley over access to the road serving the mill. The argument escalated over years. On May 11, 1943, the two men met at the road, and Keys shot and killed Bagley during the confrontation. Keys turned himself in. At trial, he was convicted of manslaughter and sentenced to ten years at San Quentin State Penitentiary.
His wife Frances Keys wrote to attorney Earle Stanley Gardner — best known as the creator of fictional defense attorney Perry Mason — who investigated the case and surfaced facts not presented at trial. His intervention led to Keys's release after five years; he later received a full pardon. After returning to his ranch, Keys erected a stone marker at the site of the shooting inscribed: 'Here is where Worth Bagley bit the dust at the hand of W. F. Keys, May 11, 1943.' The original marker was damaged by vandals and is now in storage at the park; a replica stands in its place at the exact location.
The adjacent Wonderland Ranch, set against the Wonderland of Rocks formation, is a separately deteriorated structure — its pink stucco walls and scattered outbuildings visible from the trail. The Wall Street Mill is considered the best-preserved two-stamp mill in Joshua Tree National Park.
Sources
The paranormal reputation of the Wall Street Mill and Wonderland Ranch is anchored in the specificity of what happened here on May 11, 1943, and the physical fact of the monument Keys left. A stone marker reading 'Here is where Worth Bagley bit the dust' is not how most killings are commemorated; Keys's decision to erect it after his pardon — whatever his intent — created a site where the act is permanently inscribed in the landscape.
Visitors and investigators describe shadowy figures at the periphery of vision near the mill structure. The claims tend to be directional: movement near the mill frame itself, or near the open ground where the bunkhouse stood. The Wonderland Ranch ruins — the pink-walled structure adjacent to the boulders — generate a separate category of unease, described as more psychological than visual: a strong and sustained sense of being observed.
The auditory claims are the most distinctive. The stamp mill is long since silent; its two-stamp machinery was last operated by Keys decades ago. Visitors have reported hearing what they describe as the rhythmic sound of the mill working — metal on metal, the repetitive percussion of a stamp process — originating from the ruins at dusk. This kind of functional-ghost-of-industry claim appears at other historic industrial sites and may reflect the acoustic properties of metal structures in desert wind conditions as easily as paranormal phenomena.
Cell service is minimal on this trail. The limited connectivity and the stark isolation of Queen Valley after dark are documented conditions that investigators and park visitors alike note contribute to the site's unsettling character.
Notable Entities
A roughly 2-mile round-trip walk to the best-preserved gold ore stamp mill in Joshua Tree National Park. The route passes the replica monument marking where Keys shot Bagley in 1943, the two-stamp mill machinery Keys relocated from Pinon Wells, and the pink-walled Wonderland Ranch ruins adjacent to the Wonderland of Rocks formation.

Great Smoky Mountains National Park preserves 522,427 acres of southern Appalachian terrain across Tennessee and North Carolina. The land was the heart of the Cherokee Nation before forced removal in 1838 along what became the Trail of Tears, and home to Appalachian Scots-Irish and English settler communities through the early twentieth century. Congress authorized the park in 1926; it was formally dedicated by Franklin D. Roosevelt on September 2, 1940.
