Giant sequoia are much more recent in the fossil record, appearing 25 million years ago. They grow only in 75 groups across 35,600 acres in California, near the Sierra Nevada mountains. These groups were formed as a protection from logging. The most famous area with giant sequoia trees is Sequoia National Park. The park was made as the second national park, after the Yellowstone in 1980. The Sequoia National Park is managed with Kings Canyon National Park. Together, the two parks are called Sequoia and Kings Canyon National Parks. Several trees in Sequoia National Park have even been named, for example General Grant, the Grizzly Giant or General Sherman.
