The Lost Burro Mine is one of the best-preserved historic gold mining sites in Death Valley National Park, California. Located in a remote draw at the northern end of the mountain range separating Hidden Valley from Racetrack Valley (near Teakettle Junction in the Ubehebe Mining District), the mine sits in rugged terrain accessible only by high-clearance 4WD vehicles via a rough 1-mile dirt track off the Hidden Valley road. Its isolation has helped protect the site from vandalism, making it a fascinating glimpse into early 20th-century prospecting life.
Discovery (1907)
The story of the Lost Burro Mine began on April 18, 1907, with a classic tale of serendipity. Prospector Bert Shively, while searching for his stray burros in a remote canyon, picked up a rock intending to throw it at the animals to get their attention. Instead of tossing it, he noticed the rock was laced with visible free gold. Surface assays from the outcroppings reportedly ran from $40 to $1,000 per ton — incredibly rich values for the era.
Shively quickly filed six claims and partnered with others, securing options worth around $45,000. The accidental discovery turned the site into one of the most promising gold properties in the Ubehebe District (an area otherwise known more for lead, silver, and copper).
Early Development and Peak Years (1907–1910s)
Despite the financial panic of 1907, work continued at the Lost Burro, regarded as one of the richest claims in the district. Ore samples averaged high gold values (some reports cite up to $80–$1,450 per ton in early assays), and the mine attracted multiple ownership changes and optimistic plans.
By the 1910s, development included short tunnels along the vein, with ore intersections averaging $25 per ton in later reports. Foundations were laid for a five-stamp mill and cyanide plant, intended to process ore on-site, with water piped in from Burro Spring (about 7.5 miles northeast on Tin Mountain) via a 2-inch pipeline. Remnants of this pipeline — along with rusted oil drums, tin cans, old chairs, and other debris — still litter the site.
The mine’s greatest production likely occurred between 1912 and 1917, though official records are sparse. It stands out as the only exclusively gold-bearing property in the Ubehebe District.
Later Operations and Decline (1920s–1970s)
The mine changed hands several times over the decades and was worked intermittently. In 1942, claims were relocated, and further amendments occurred in 1948 and 1970. A small amount of recorded production (about 255 ounces of gold between 1935 and 1942) exists, but unofficial estimates suggest the total lifetime output may have approached $100,000 in gold value.
Operations wound down by the 1970s, and the site was eventually incorporated into Death Valley National Park, where all mining claims became inactive.
Modern Legacy
Today, the Lost Burro Mine features a remarkably intact wooden cabin (in good condition, with stories of a “curse” leading some visitors to return removed artifacts), an outhouse, multiple adits (some used for storage), a one-chute ore bin, mill foundations stairstepping down the hillside, scattered machinery (including a small retort/smeltor and sluice box remnants), and tailings piles.
The site’s remoteness — requiring a challenging 4WD journey often combined with trips to the nearby Racetrack Playa — has kept it well-preserved and largely free of modern vandalism. Visitors are reminded to leave everything as found, as the area is protected wilderness.
The Lost Burro Mine remains a testament to the tenacity of Death Valley prospectors — turning a frustrated burro chase into a legendary gold story in one of the harshest environments on Earth. Always check current road conditions and permits with the National Park Service before visiting!
