The slopes get rockier the closer you get to the Patriarch Grove. The dense, resinous wood of the Bristlecones makes them resistant to fire and to insect infestation. Few other plants grow where the ancient Bristlecones do, leaving the squatty pines to guard the heights largely alone. Although the Bristlecones are the oldest single-organism living things on earth, it's important to recognize that clonal colonies of creosote bushes, aspen trees, and Norway spruce have been dated as much, much older.
