In many ways, Great Basin National Park is a park of extremes. The difference between the park’s highest point and lowest point is a staggering 6,235 feet (1,900 meters). While the lower valley is mostly a desert landscape, the mountainous areas of the park are home to some of the oldest trees on the planet. Some of these amazing bristlecone pine trees are over 4,000 years old. It’s just another reason why the Great Basin National Park is so incredible.
