Calaveras became a State Park in 1931 to preserve the North Grove of giant sequoias. This grove includes the “Discovery Tree”, also known as the “Big Stump”, the first Sierra redwood noted by Augustus T. Dowd in 1852. This area has been a major tourist attraction ever since, and is considered the longest continuously operated tourist facility in California.
