Wikipedia Abstract

Pinus aristata, the Rocky Mountain bristlecone pine, is a species of pine native to the United States. It appears in the Rocky Mountains in Colorado and northern New Mexico, with an isolated population in the San Francisco Peaks in Arizona. It is usually found at very high altitudes, from 2500–3700 m, in cold, dry subalpine climate conditions, often at the tree line, although it also forms extensive closed-canopy stands at somewhat lower elevations.

Usage [3]  A tan or green dye is obtained from the needles; The tree could be the source of antioxidants that contribute to long life; The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat; Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile; The resins are obtained by tapping the trunk, or by destructive distillation of the wood; In general, trees from warmer areas of distribution give the higher yields; Turpentine consists of an average of 20% of the oleo-resin; Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc; Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc; Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc. Wood - light, soft, not strong. Used for fuel and mining timber;
