The Searles Valley


Road to Trona


Trona, home to Searles Lake playa, is located in the Searles Valley on Hwy 178 in the Greater Mojave Desert. Searles Lake is one of a chain of pleistocene lakes which were formed during the Ice Ages. The dry lake bed contains a plethora of sodium and potassium minerals of the carbonate, sulfate, borate and halide classes, due to long sedimentation and evaporation processes which occurred over a period of about 150,000 years.

The dry lake also contains the Trona Pinnacles National Natural Landmark which consists of more then 500 tufa spires. Trona Pinnacles has been the site of many movies and commercials because of its prehistoric mystical appeal. Star Trek 5, Tim Burton's Planet of the Apes, and Disney's Dinosaur all contain scenes filmed at the Trona Pinnacles tufas.

In 1862 John W. Searles discovered Borax on the dry barren surface of Searles Lake while prospecting for gold and silver with three other people in the slate mountain range. But his discovery went unrecognized.

After seeing Francis (Borax) Smith's operation of Borax recovery in Nevada in 1872, Mr. Searles realized the value of what he had discovered at Searles Lake. In 1873 John W. Searles staked a claim to 640 acres of lake and formed The San Bernardino Borax Mining Company. Mules were used to haul the Borax to San Pedro.

In 1897 soon after John Searles' death The San Bernardino Borax Mining Company was sold to Pacific Borax Company which was owned by Francis (Borax) Smith. Pacific Borax shut down the Searles Lake operation.

Searles Lake and Trona have seen many changes.

In 1914 Trona Railway Company completed 31 miles of track to Trona from the Searles Station junction with the Southern Pacific Railroad. American Trona Corp. established the company owned town of Trona.

A main residential street existed for a while, called "Tent City" because of the tent type houses that the residents lived in back then. Around 1916 a few houses were built for the upper management employees and their families. Some of these houses are still standing and some are still being lived in on Panamint and Magnolia streets. The History House, which is open to the public at 83001 Panamint St., is one of the first houses built in Trona.

Today one of Trona's main sources of income is still mining operations. On March 18, 2004, all operations of IMC Chemicals were sold to Sun Capital Investments and the operations in Searles Valley was renamed "Searles Valley Minerals, Inc." The small desert town of Trona holds a lot of history and offers modern living at an affordable price. Over the years not only has Trona preserved its history, it has also grown and changed with the times.
