Muir Woods is a remnant of ancient coastal redwood forests that once blanketed many northern California coastal valleys before the 1800's. (Muir Woods along with the Redwood Creek watershed are part of the Golden Gate International Biosphere Reserve.)
The Redwood Tree can grow to 379' tall, live up to 2,000 years and reach up to 22 ft in diameter with bark up to 12 in. thick.
The Giant Sequoia are closely related, have larger bulk and live even longer, but are not as tall. The Giant Sequoia can be seen in Yosemite and Sequoia and Kings Canyon National Parks.
