Mount Baldy, located in Arizona's White Mountains on the Fort Apache Indian Reservation, is an eroded mountain peak whose summit is above sea level. Its name was given to it by locals because it lacks trees on the upper ridge, giving it a baldlike appearance. Mount Baldy is home to the Sunrise Ski Area. The mountain is not part of a range, just a single prominent peak whose flanks are gentle and peak is rounded, not rugged. This is the same for most of the White Mountains, a geologically old range once as high as the Alaska Range, but that has been eroded away over the eons. Mount Baldy is home to a bristlecone pine forest, and some consider the White Mountains as a Rocky Mountains extension due to similar averages in elevation, tree species, animals, and weather.
