The roots of the Pacific Coast Borax Company lie in Mineral County, Nevada, east of Mono Lake, where Smith, while contracting to provide firewood to a small borax operation at nearby Columbus Marsh, spotted Teels Marsh while looking westward from the upper slopes of Miller Mountain where the only nearby trees were growing. Eventually, to satisfy his curiosity, Smith and two assistants visited Teels Marsh and collected samples, that proved to assay higher than any known sources for borate. Returning to Teels Marsh, Smith and his helpers staked claims and laid the foundation for his career as a borax miner. With the help of his older brother, Julius, who came west from the family home in Wisconsin, and financial support from the two Storey brothers, operations began in 1872 under the name, Smith and Storey Brothers Borax Co. When the Storey brothers' interests were subsequently acquired in 1873, the name was shortened to Smith Brothers Borax Co. A few years later it was changed again to Teel's Marsh Borax Co. In 1880, the separate and previously existing Pacific Borax Company was acquired by Smith. Frank Smith also developed holdings with his business associate William Tell Coleman at the Harmony Borax Works as well as the Meridian Borax Company, which were subsequently combined to form the Pacific Borax, Salt & Soda Company in 1888. The Pacific Coast Borax Co. name was not adopted until Smith acquired all of Coleman's borax interests in central Nevada and California, after Coleman's bankruptcy, and incorporated them all under the new company name in 1890.
The company established and aggressively developed and marketed the 20 Mule Team Boraxtrademark in order to promote the sale of its product. The name derived from the 20-mule teams that were used to transport borax out of Death Valley in the 1880s from Harmony Borax Works near Furnace Creek Ranch, owned by William Tell Coleman at that time and sold to Smith in 1890. They also produced Boraxo hand soap. The radio version of Death Valley Days ran from 1930 to 1951. The TV series Death Valley Days was hosted at one point by "Borateem-pitchman" and future U.S. President Ronald Reagan.
In Death Valley Junction, California in 1923-24, the Pacific Coast Borax Company constructed their Civic Center at a cost of $300,000. Designed by architect Alexander Hamilton McCulloh, the U-shaped complex of Spanish Colonial Style adobe buildings included company offices, a store, an employee dorm, a 23-room hotel, dining room, lobby, gymnasium, billiard room and ice cream parlor. At the northeast end of the complex was Corkhill Hall, a recreation hall used as a community center for dances, church services, movies, funerals and town meetings. Remodeled in 1927, the Civic Center became the Amargosa Hotel. In 1967, Corkhill Hall became Marta Becket's renowned Amargosa Opera House.
U.S. Borax
In 1956, the Pacific Coast Borax Company merged with United States Potash Corporation to form U.S. Borax, which itself was acquired by Rio Tinto Minerals in 1967. As a wholly owned subsidiary, the company now is called Rio Tinto Borax and continues to supply nearly half the world's borates. In 1988, U.S. Borax sold its flagship Boraxo, Borateem and 20 Mule Team product lines to Dial Corporation. It continues to operate the Rio Tinto Borax Mine, which is the largest open-pit mine in California next to the company town of Boron, in the Mojave Desert east of Mojave, California. The Trona operation later became part of Searles Valley Minerals.
