The Lost Gold course is one of two Jack Nicklaus designs at Superstition Mountain, a private club located just east of Phoenix (Nicklaus designed Lost Gold alongside his son, Jackie). Though the fairways are generous, the Lost Gold is a tougher test than the Prospector course, with smaller greens and strategically placed bunkers. The front nine has many parallel fairways separated by bunkers, while the back nine opens up more into the desert, with fantastic views of Superstition Mountain.
