Muir Woods National Monument

Muir Woods National Monument (north of San Francisco) contains the world’s tallest trees. Coastal redwoods can grow up to 380 feet in height – the equivalent of a 35-story building! Although the trees are tall, the roots are shallow and extend only 8 feet below the surface. Amazingly these large trees have pine cones the size of marbles, and seeds the size of oatmeal flakes. Muir Woods is so inspirational that it was chosen to host the first United Nations Peace Conference in 1945.
Many of the redwoods in the park are over 1,000 years old. The cross section shows a redwood tree that fell in 1930. The center point marks when the tree was born. The second white ring from the outer edge marks 1492, when Columbus discovered America. The first white ring from the outer edge marks 1776, when the Declaration of Independence was signed. The outer edge marks when the tree fell down at 1,021 years old.
