The Upper and Lower courses are very different, being built on two distinct
geological formations. Tillinghast designed them as "Dual Courses" which were to be "equally sought after as a matter of preference." The Lower is spread out over rolling parkland, the remains of a
terminal moraine deposited during the last
glaciation about 18,000 years ago. The Upper runs along a ridgeline known as Baltusrol Mountain, the east side of the
First Watchung Mountain (Orange Mountain) that was formed from
vast lava flows about 200 million years ago. Both courses have ponds and other man-made and natural hazards that come into play. On the Lower Course, the 4th hole and the 18th hole have ponds, and on the Upper Course, the 9th and the 13th holes have ponds. The 10th, 13th, and 15th holes have creeks in play. As of 2010, Baltusrol Golf Club holds the distinction of being the only two-course club to ever host both the U.S. Men's and Women's Open Championships on both of its courses.
Lower Course The Lower course from the black tees measures and is a par 72, but for the 2005 PGA Championship, the course measured and was par 70. From the blue tees, the course measures and is par 72. From the green tees, the course measures 6,652 yards and is par 72. From the white tees, the course measures and is par 72. From the red tees, the course measures and is par 73. In its listing of the "Top 100 Courses in the U.S.", GOLF Magazine selected the Lower Course as 22nd in 1995, 1997, and 1999. The three signature holes of the Lower Course are the fourth, a par three of where the player must hit his or her ball over the pond to a two-tiered green; the seventeenth, a par five of where
John Daly is the only player to ever reach the green in two strokes (later, Tiger Woods fired his second shot over the green in two shots at the 2005 PGA Championship); and the eighteenth, a par five of famous for spectacular performances by Furgol, Nicklaus, Mickelson and Jason Day.
