The Ancient Bristlecone Pine Forest is located in the White Mountains just north of Death Valley National Park. The Bristlecones here include the oldest living trees on the planet. They are only found at about 10,000 ft (3048 m) and above in a few isolated locations. There are a number of nature trails providing paths through the forest … the erosion caused by human presence off the trails results would result in many additional tree losses … natural loss of soil being one of the main causes of Bristlecone mortality. This view is looking SE across the Owens Valley (unseen) towards the Sierra Nevada.
