Eagle Borax Works, Historic borax processing facility in Death Valley, Inyo County, US.

Eagle Borax Works is a ruined borax-processing site near Bennetts Well in Death Valley, established in 1882. What remains are the fire box of a boiler, an earth mound where a stone workers' building stood, and traces of open tanks used to dissolve and crystallize borax. Partly refined borax was loaded here for hauling to Daggett, California.

Isidore Daunet, J.M. McDonald, M. Harmon and C.C. Blanch founded the Eagle Borax Works near Bennetts Well in 1882, the first borax works in Death Valley, after Daunet found the borate deposit during an 1880 crossing. Partly refined borax went to Daggett by 12-mule teams hauling two wagons through Panamint Valley. Operations ended in 1884 when Daunet, swindled out of $11,000 and facing divorce, killed himself. The property passed to U.S. Borax, then Borax Consolidated in 1922, the Death Valley Hotel Company in 1956 and the National Park Service; it was listed on the National Register on December 31, 1974.

The site preserves a tale told by prospector "Shorty" Harris of a Chinese worker at the works who, crossing the Panamint Mountains, reportedly found a rich gold vein in a 15-pound rock. The property later passed to the U.S. Borax Company as a mining reserve, then to Borax Consolidated, Ltd. in 1922, and was sold to the Death Valley Hotel Company in 1956 before reaching the National Park Service.

The ruins are located within Death Valley National Park and can be reached on foot from a nearby pullout. Informational signs explain how the extraction and crystallization process worked, helping visitors understand the technical operations that took place here.

Isidore Daunet found the borate deposit during an 1880 Death Valley crossing in which three companions died; he survived by killing one of the party's animals and drinking its blood. A separate tale, told by prospector Shorty Harris, holds that a Chinese worker at the works found a rich gold vein in a 15-pound rock in the Panamint Mountains.
