The Giant Sequoias is the largest living thing on earth. They are found in few places, among them is the Mariposa Grove of Yosemite National Park.

It is difficult to appreciate the size of the giant sequoias because neighboring trees are so large. The largest of the sequoias are as tall as an average 26-story building, and their diameters at the base exceed the width of many city streets. As they continue to grow, they produce about 40 cubic feet of wood each year, approximately equal to the volume of a 50-foot-tall tree one foot in diameter.

The ages of the large sequoias are unknown, but it is estimated that these giants are between 1800 and 2700 years old.
