The Discovery Tree stump is located in the popular North Grove of the Calaveras Big Trees State Park. The Discovery Tree, a Giant Sequoia (Sequoiadendron giganteum), was first noted by Augustus T. Dowd in 1852 and felled in 1853, leaving only a giant stump which is the only remainder of the tree. The tree measured 24 feet (7.3 meters) in diameter at its base and was 1,244 years old when felled.
Calaveras Big Trees State Park with an area of about 26 square kilometers (6,400 acres) and a major tourist attraction since 1852, when the existence of the Giant Sequoias trees was first widely reported, is located 4 miles (6.4 km) northeast of Arnold, California, in the middle altitudes of the Sierra Nevada in Calaveras County. It became a state park in 1931 and it is considered the longest continuously operated tourist facility in California.
