The Wall Street Gold Mill is a very interesting and rare example of a complete small desert gold mill. And to boot, it is only a short walk inside the backcountry of Joshua Tree National Park.


Once owned by renown prospector and rancher Bill Keys, this mill was a custom mill, meaning that it processed ore in batches for many local area mines. Keys started up the mill here in 1932 after purchasing the stamps from New Eldorado Company at Pinyon Well and relocating it from there. The mill had been working at Pinyon Well since 1891. Keys worked the mill intermittently until 1942 when WWII closed all the gold mines. His son took over and operated it for a brief time starting in 1949. Bill last ran the mill for about a month in 1966. It was acquired by the National Park Service in 1971 from the Keys estate.


As a side note, Bill also shot a man named Worth Bagely along the trail here. As the story goes in the late 1930s, a retired lawman, Bagley, moved in to a nearby homestead. For reasons that remain unclear, Keys and Bagley had some serious ill feelings between them. Some of Keys cattle were shot and Bagley reportedly became obsessed with murdering Keys. The two had a gun battle and Bagley was shot and killed. Keys claimed self-defense but was convicted of manslaughter and send to San Quentin. He was paroled in 1948. He eventually was pardoned in 1956. Keys died in 1969 and is buried at Keys Ranch.


We have visited the mill a few times over the years. Even walking out there at night once. It is a great place.
