Above the Tree Line

In Arizona, the tree line is just above 11,000 feet. There are only a handful of peaks that reach that elevation in the entire state. As you go north, the tree line drops until in this photograph, the tree line is about 3,000 feet and it is about the same as the snow line. Further north, out on the tundra, the tree line drops to sea level and no trees can grow. We don't have any mountains in Arizona that look remotely like these in Alaska.
