"Dr. J. K. Suckow was drilling a well for water 4½ miles northwest of Boron when he discovered colemanite, a borax ore, in October 1913. After his discovery, mining claims, mostly placer, were staked in the area. The Pacific Coast Borax Company, upon recommendation of its field engineer, Clarence Rasor, acquired many of these claims, including the discovery well. The company then started explorations to determine the extent of the ore body. Suckow continued to have an interest in the area, working prospects east of his discovery well.

"In 1924, anxious to repeat his good fortune, Suckow sank a shaft one-half mile away from his first, and he struck basalt at 180 feet (55 m). The Pacific Coast Borax Company prospected in the same area, with almost the same results: basalt at 190 feet (58 m). However, persistence paid off. That same year Suckow sank another shaft just a little south of his last one and found a 70-foot (21 m) thick bed of colemanite at 210 feet (64 m). In 1925 the Suckow Chemical Company produced a few hundred tons of colemanite from this shaft.

"In the Spring of 1925, William M. Dowsing and J. L. Hannan discovered a huge deposit 120 feet (37 m) thick just 1½ miles west of Suckow's shaft, which they kept a secret until its extent was proven. Sold to the Pacific Coast Borax Company in early 1926, it became known as the Baker Mine. Beginning production in 1927, it yielded a substantial percentage of the borates produced in the Kramer District until 1935.

"Production began in December, 1929, at the Suckow Mine, located near the Baker Mine. Suckow Borax Mines Consolidated, Ltd. shared half-interest as tenant in common of the Suckow Mine with Borax Consolidated, Ltd. The two companies became involved in litigation which resulted in the closure of the mine in 1932. It was reopened in 1935 as the West Baker Mine with the Borax Consolidated, Ltd. as owners."

The first post office at Boron opened in 1938.


A large borax deposit was discovered in 1925, and the mining town of Boron was established soon thereafter. This borax deposit is now the world's largest borax mine. It is owned by Rio Tinto Minerals (formerly U.S. Borax). It is operated as an open-pit mine, the largest open-pit mine in California. This mine supplies nearly half of the world's supply of refined borates. Rio Tinto Minerals is Boron's primary employer, employing over 800 people.

Six miles east of Boron, across the county line in San Bernardino County, is the world's largest solar power production facility. The Kramer Junction Company (KJC) is the managing general partner of the five 30 megawatt Solar Energy Generating Systems (SEGS) facilities in the Mojave Desert at Kramer Junction, California. Together with its wholly owned subsidiary, KJC Operating Company, KJC operates and manages these facilities (SEGS III-VII). These units generate enough electricity to provide the electrical needs of 30,000 to 40,000 homes without the use of fossil fuels.

  • Law enforcement

    Law enforcement services are provided by the Kern County Sheriff's Department. From 1933 to 1954 personnel from the Mojave substation met the law enforcement need of the Boron area. The first actual office space occupied by the sheriff's office in Boron was a quonset hut shared with the fire department in the 12200 block of Boron Avenue. This continued until 1963 when the sheriff's office established the substation building at 26949 Cote Street. This building housed a small jail and the court in Boron, which operated one day a week.

    Fire services

    In 1969 the new Boron station 17 opened at 26965 Cote Street. This fire station is operated by the Kern County Fire Department.


    Boron schools are part of the Muroc Joint Unified School District. The local Boron schools include the K – 6 grade West Boron Elementary School, and the 7 – 12th grade Boron High School. Boron High School's mascot is the Bobcat. Boron's first school, Gephart School was built in 1929. It burned to the ground in 1994.


    Boron's original church building was completed for the First Baptist Church in 1940. Boron currently has eight churches. They are the Assembly of God Church, the Boron Bible Church, the Church of Christ, the Church of Jesus Christ of Latter-day Saints, the First Baptist Church of Boron, the Jesus Name Tabernacle United Pentecostal Church, St. Joseph's Catholic Church and Christians in Faith Church.

    Notable residents

  • Boron was the home of "Walking George" Swain, whose penchant for walking made him a legend. George earned his name as "Walking George" because he never owned a car, or house, and walked to and from work—from his home, which was always rumored to be just a hole in the desert. He supposedly kept himself warm at night with a covering of newspapers. His wardrobe was always the same: wrinkled shirt and pants with well-worn boots. Swain was a chemist at the borax plant in Boron. He attended local events and often played the piano for entertainment. He taught piano to children in Boron and played at the Baptist Church. On his 59th birthday in 1978 an article about George appeared in the Los Angeles Times. By May 1979 he was featured on the TV show Real People. He died on April 25, 2000.
  • Boron was home to Pancho Barnes from 1966 to 1974. Pancho was a world-renowned air race and stunt pilot during the 1920s and 1930s. She is better known, however, for being the matron of the Happy Bottom Riding Club. Pancho was forced to move when, during a heated dispute with Edwards Airforce Base over the expansion of one of the nearby bases runways, the club (officially Rancho Oro Verde) mysteriously burned down. Years later Pancho moved to Boron from Gypsy Springs when her age no longer allowed her to properly tend to her ranch. Pancho died in Boron during the spring of 1974.
