고도 11,000 feet에 이르는 the Ancient Bristlecone Pine Forest Schulman Grove에는 아직도 살아있는 5800살에 이르는 나무가 있다. 죽어 고목이 된 나무는 12000년에 이르는 것도 있다고 한다. University of Arizona의 Schulman 교수 등이 세계에서 가장 오래된 나무를 밝혀냈다. 탄소동위원소 특정기법에 5800살에 이르는 나무의 나이테를 자료로 사용하여 탄소동위원소 연대 특정 기술이 더 정교 해졌다. 이곳의 나무의 나이테덕에 인류의 역사를 다시 써야할 판이다.

The Ancient Bristlecone Pine Forest is a protected area high in the White Mountains in Inyo County in eastern California.

.

Geography - The forest is east of the Owens Valley, high on the eastern face of the White Mountains in the upper Fish Lake-Soda Spring Watershed, above the northernmost reach of the Mojave Desert into Great Basin ecotone. The forest's mountain habitat is in the Central Basin and Range ecoregion (EPA) and Taiga and Boreal forest ecoregion (WWF). The Patriarch Grove is the source of Cottonwood Creek, a designated Wild and Scenic River.

.

Ecology - Pinus longaeva (commonly referred to as the Great Basin bristlecone pine, intermountain bristlecone pine, or western bristlecone pine) is a long-living species of bristlecone pine tree found in the higher mountains of California, Nevada, and Utah. Methuselah is a bristlecone pine that is 4,853 years old and has been credited as the oldest known living non-clonal organism on Earth. To protect it, the exact location of this tree is kept secret. In 1987, the bristlecone pine was designated one of Nevada's state trees. The Great Basin bristlecone pine (Pinus longaeva) trees grow between 9,800 and 11,000 feet (3,000–3,400 m) above sea level, in xeric alpine conditions, protected within the Inyo National Forest. Limber pine (Pinus flexilis) also grow in the forest.

Methuselah - The Methuselah Grove in the Ancient Bristlecone Pine Forest is the location of the "Methuselah", a Great Basin bristlecone pine that is 4,853 years old. It is considered to be the world's oldest known and confirmed living non-clonal organism. It was temporarily superseded by a 5,062 year old bristlecone pine discovered in 2010. In May 2017 however, Dr. Peter Brown removed this tree from his database of old trees because the tree and core sample could not be found. "Methuselah" is not marked in the forest, to ensure added protection from vandals.

.

Visiting - The Schulman and Patriarch groves are located about 30 mi (48 km) from Bishop, California. The Ancient Bristlecone Pine Forest is generally open from mid-May through the end of November, weather permitting.

Schulman Grove and Schulman Grove Visitor Center – daily interpretive talks and natural history lectures mid-June through Labor Day, and hiking trails.

.

Patriarch Grove – home of the world's largest bristlecone pine, the Patriarch Tree, and a self-guided nature trail.

Methuselah Grove trail - The Methuselah Grove trail starts from the visitor center at 9,846 feet and makes a 4.5-mile (7.2 km) loop that includes the side valley of the Methuselah Grove where the oldest tree lives, a high section looking out eastward over Nevada's basin-and-range region, and side trails to old mining sites. Numbered natural-history markers are explained by a booklet.

.

Fire - On September 4, 2008, an arsonist set fire to the Schulman Grove Visitor Center and several bristlecone pines. The building and all the exhibits within were destroyed. Activities to rebuild the center began the next day and are now complete.
