Another view of a 'redwood cathedral' at Big Basin State Park in California.
This beautiful arrangement of a ring of redwood trees occurs when a giant coast redwood dies. New trees sprout from the base of the trunk from adventitious buds, resulting in this circular arrangement.
It's really pretty stunning to see in person.
These trees are relatively young -- the oldest and tallest trees at Big Basin are over 2000 years old and approach 100 meters in height (over 300 feet).
