Hidden in the upper reaches of the Pacific coast of Northern California, Redwood National Park contains some of the tallest and most ancient trees in the world. We are talking about Sequoia sempervirens - better known as coastal sequoias. They reach their phenomenal height of up to 115 meters, intertwining at the roots and creating a supportive network that allows them to stand despite storms and other weather events. There are many such moss-covered wonders growing in the national park, but this is only the beginning.
