Hyperion is a coast redwood (Sequoia) in California that was measured at 115.85 m (380.1 ft), which ranks it as the world’s tallest known living tree. The Park also houses the second tallest tree Helios, and the third tallest Icarus. It is estimated that Hyperion is 600 years old, while others report it to be roughly 700–800 years old.
The exact location of Hyperion is kept secret to protect the tree from damage.
In Greek mythology, Hyperion, – “The High-One” – was one of the twelve Titan children of Gaia (Earth) and Uranus (Sky) who, led by Cronus, overthrew their father Uranus and were themselves later overthrown by the Olympians. With his sister, the Titaness Theia, Hyperion fathered Helios (Sun), Selene (Moon) and Eos (Dawn). Keats’s abandoned epic poem Hyperion is among the literary works that feature the figure.
