Bristlecone Pines: these trees are in the Patriarch Grove, more than 11,000 feet above sea level, in the White Mountains of California. Nearby White Mountain is 14,246 feet - 4,342 meters - in elevation. Some of the trees are more than 4,000 years old. Many of them have only a narrow strip of living bark to sustain them in this otherwise rather barren landscape, but this beautifully weathered specimen is definitely dead.
