A 1918 stereograph of the Wawona Tree, a famous giant sequoia (227 ft or 69 m in height and 90 ft or 27 m in circumference) that stood in Mariposa Grove, Yosemite National Park, California, United States. The tunnel was cut through the tree in 1881, enlarging an existing fire scar, making the tree a popular tourist attraction. Often travelers would come to have their picture taken either driving through the tunnel or standing underneath the tree. When it collapsed in 1969, its estimated age was 2,300 years.Photo credit: Keystone View Co.
