Originally known only to nomadic Indians during yearly mountain crossings, Boulder Hot Springs centers on waters that bubble out of the mountains just south of the site at temperatures ranging from 120 to 182 degrees and were known worldwide for their healing powers. The hotel there was founded in the early 1880's by A.C. Quaintance as a haven for local miners and ranchers who, after laboring long, hard hours, found respite and relaxation in these waters. In 1909, the main building and baths that stand today were rebuilt in California Mission style by California millionaire James A. Murray. Throughout its history, Boulder Hot Springs served as a resting place and resort for presidents, the well to do, and ordinary people alike. In 1935, an earthquake destroyed the Olympic-size swimming pool. Beginning in 1940 and for the next 20 years, Boulder Hot Springs bustled with activity under the management of Pappy Smith, who used the name Diamond S. Ranch Hotel. Its significance since the last century has lain in its environment, open spaces, clean air, clear skies, healing waters, and the quiet solitude and mountain splendor reflected in the elegance and grace of the old hotel.
