Founded 1850

Of the 27 original counties in the state, Mariposa County is the largest. It has been called the Mother of California Counties due to the fact that 12 other counties, either in part or all, have been carved from its borders. Among them are: Fresno, Inyo, Kern, Kings, Los Angeles, Madera, Merced, Momo, San Benito, San Bernardino, San Luis Obispo and Tulare.

The name came from Mariposa Creek which was named by Spanish explorers when they found large groups of butterlifes in the foothills in 1806. Butterflies in Spanish is Mariposas. A Butterfly Days parade was held for many years to celebrate the annual arrival of the migrating Monarch butterflies.

The Gold Rush
Though removed from the main areas, the county is located at the southern end of the Mother Lode region. During this era, much gold was found and brought out from county streams and mines. A number of museums depict the county's role in the Gold Fever era.
