The crew of this Bonanza are enjoying a beautiful sunset over the White Tank Mountains in Arizona. Most of the White Tank Mountain Regional Park is made up of the rugged and beautiful White Tank Mountains, which is a freestanding range separating the Phoenix Basin of the Salt River Valley from the Hassayampa Plain. The range rises sharply from its base, at 1,400 feet above sea level, in a series of rocky ridges and fault lines to peaks of over 4,000 feet.
