Coeur D' Alene Resort - Idaho, U.S.A.

The Coeur D'Alene Resort Course is on Lake Coeur D'Alene, located in Idaho's upper panhandle some 30 miles from Spokane. Designed by Scott Miller and opened in 1991, the experience is that of a manicured lakeshore park with immaculate bent-grass fairways and bluegrass rough straddled by rocky outcroppings and slender rods of Austrian pines. Players are taken to the course from the resort on mahogany launches named Eagle and Double Eagle, with a lakeside practice range where floating balls are hit to floating targets in the water. Several holes play along the shore of the lake and over Fernan Creek. But what makes Coeur D'Alene world-famous is the par-three 14th hole, which features the world's only floating green. Built of foam-filled concrete, the 15,000-square-foot, 7,500-ton green comes complete with a pair of bunkers, small pines, and a bed of red geraniums. Each day the yardage is adjusted from 100 to 175 yards offshore by moving the green using cables and winches. After the tee shots, players are ferried out to the green, where the boat's skipper rakes the sand, tends the flag-stick, and records the scores.

Old Works Golf Course - Montana, U.S.A.

Old Works Golf Course is laid out over what had once been the site of one of the world's largest copper smelters, which began production in 1884 to process the ore from the Butte mines. Designed by Jack Nicklaus in 1994 and opened as a public course, Old Works transformed what had been an EPA Superfund site into a green expanse offset by swirling bunkers filled with jet black slag, a by-product of the smelting process. Nicklaus cleverly incorporated remnants of the actual 19th-century Old Works into the design, including the stone furnaces of the Calciner that line the par-five third hole and the massive brick flue that gapes from the hillside above the fourth. The elevated tees offer views of the Anaconda-Pinder Mountains while Warm Springs Creek comes into play on the first, 10th, and 11th holes. The holes have names such as Flue #5, Convertor, Copper Kings, and Anode. Old Works plays a hefty 7,700 yards from the back or "Slag" tees.
