In the shadow of Wheeler Peak at Great Basin National Park in Nevada, ancient bristlecone pine trees grow on rocky glacial moraines – creating a surreal and beautiful landscape. Bristlecone pines are the world’s longest living tree. At Great Basin, a 4,900+ year old tree was removed from the Wheeler Peak grove in 1964.
