Calaveras County was one of the original counties of the state of California, created in 1850 at the time of admission to the Union. Parts of the county’s territory were reassigned to Amador County in 1854 and to Alpine County in 1864.

The county’s geography includes beautiful landmarks, rolling hills, and giant valleys. It is also known for its friendly communities and businesses such as agriculture management and construction engineering. It has numerous caverns, such as Mercer Caverns, California Cavern and Moaning Cavern that are national destinations for tourists from across the country. Other attractions include a thriving winemaking industry, including the largest of the Calaveras wineries: Ironstone Vineyards, mountain sports recreation, and the performing arts.
