The ancient bristlecone pine forest high up in the White Mountains on the eastern slopes of the Sierra Nevada in California grows at an altitude between 3000 and 3400 m (9800 and 11,000 ft) under arid high alpine conditions. They are the oldest living trees in the world.
A nighttime bristlecone pine forest belongs to one of the most bizarre places on our planet. Although these solitary gnarled trees seem to be dead, they carry a few living branches and enjoy the nightly view into deep space.
