A Bristlecone pine
Many of the Bristlecone Pines look like they are dead, but upon closer inspection, a few branches have green needles. Some of these trees are 3000 - 4000 years old and are quite gnarled. There are 2 trails that take visitors among the trees. We took the steep, but shorter, 1-mile trail (at 10,000 feet, it had us puffing at times!).
