Heart Pine refers to the heartwood of the pine tree, which is the non-living center of the tree trunk, while the sapwood is the outer living layer which transports nutrients.
 The heartwood from the pine tree, heart pine, is preferred by woodworkers and builders over the sapwood, due to its strength, hardness and golden red coloration.
 The longleaf pine, the source of much of the available heart pine found on the market is considered a high quality timber tree, a well known source for poles, pilings, posts, sawlogs, flooring, plywood, pulpwood and naval stores (tapped for turpentine).
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.
 One member of this species, at 5067 years old, is the oldest known living non-clonal organism on Earth.
 In 1987, the bristlecone pine was designated one of Nevada's state trees.
Methuselah is a -year-old Great Basin bristlecone pine ("Pinus longaeva") tree growing high in the White Mountains of Inyo County in eastern California.
 For many years it was thought to be the world's oldest known living non-clonal organism, until it was superseded in 2012 by the discovery of another bristlecone pine in the same area with an age of years (germination in 3050 BC).
Donald Rusk Currey (January 24, 1934 – June 6, 2004) was an American professor of geography.
 While known in academia for his extensive research and exploration of relics of the ancient Lake Bonneville in the eastern Great Basin, he was best known to the public for his controversial felling of Prometheus, the oldest living non-clonal organism known at the time, while a graduate student in 1964.
The term bristlecone pine covers three species of pine tree (family Pinaceae, genus "Pinus", subsection "Balfourianae").
 All three species are long-lived and highly resilient to harsh weather and bad soils.
 One of the three species, "Pinus longaeva", is among the longest-lived life forms on Earth.
 The oldest "Pinus longaeva" is more than 5,000 years old, making it the oldest known individual of any species.
Prometheus (recorded as WPN-114) was the oldest known non-clonal organism, a Great Basin bristlecone pine ("Pinus longaeva") tree growing near the tree line on Wheeler Peak in eastern Nevada, United States.
 The tree, which was at least 4862 years old and possibly more than 5000, was cut down in 1964 by a graduate student and United States Forest Service personnel for research purposes.
 The people involved did not know of its world-record age before the cutting (see below), but the circumstances and decision-making process remain controversial; not all the facts are agreed upon by all involved.
The giant sequoia ("Sequoiadendron giganteum") is the world's most massive tree, and arguably the largest living organism on Earth.
 It is neither the tallest extant species of tree (that distinction belongs to the coast redwood), nor is it the widest (that distinction belongs to the baobab tree or Montezuma Cypresses), nor is it the longest-lived (that distinction belongs to the Great Basin bristlecone pine).
 However, with a height of 286 ft or more, a circumference of 113 ft or more, an estimated bole volume of up to 52500 ft3 , and an estimated life span of 1800–2700 years, the giant sequoia is among the tallest, widest and longest-lived of all organisms on Earth.
The Ancient Bristlecone Pine Forest is a protected area high in the White Mountains in Inyo County in eastern California.
 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.
 Foxtail Pine (Pinus balfouriana) also grow in the forest.
Cottonwood Creek originates in the Ancient Bristlecone Pine Forests of the White Mountains of eastern California.
 The creek flows eastward from below the alpine crest of the White Mountains and descends through groves of bristlecone pine, aspen and mountain mahogany, then a woodland of pinyon pine and juniper, and finally into sagebrush as the stream ends in endorheic Fish Lake Valley which is one of the contiguous collection of inward-draining basins that make up the Great Basin.
One of the ways to use a bamboo mat for S'chach (for the top of a sukkah).
 The Bamboo Mat is made from Bamboo sticks then it's cut vertical and tied with a thin string.
 Although you can use palm leaves and pine tree branches etcetera, But the Bamboo Mat can be used yearly as opposed to palm leaves and pine tree branches etcetera that can't be used yearly.
 Also another advantage is that if you will use palm leaves and pine tree branches etcetera, leaves and chips of wood might fall off from the palm leaves and pine tree branches etcetera , but if you use a bamboo mat for S'chach usually leaves and chips of wood would less likely to fall off from the s'chach Once Succot is over, it can just as easily be rolled up into about 6" in diameter depending on your bamboo mat so for example if you have a bamboo mat that's 5' x 10' it will usually be 5' feet tall, making storage and retrieval simple year after year.
