Many here have played Stone Eagle. Since Tom is one of our regular contributors, our GCA members make an effort to play his new courses. You'll find first hand opinions of all his courses here.
Stone Eagle is not considered one of Tom's best golf courses. Generally, Pacific Dunes, Barnbougle Dunes, Ballyneal, and perhaps Cape Kidnappers are considered Tom's greatest creations. Like Bill McBride says, Stone Eagle is built on the side of a mountain, and the terrain is very steep for golf. Most of the holes are routed up towards, or down away from a canyon at the top of the course, so there are quite a few parallel fairways as the best solution for course routing.
The primary weaknesses are:
1) A very demanding and hilly walk. Very few walk.
2) A less than ideal set of par 3s. All five (of 19 holes) are routed to cross unplayable terrain to get to the next playable area. Three are drop shots, and the variety of clubs used to play them is limited.
3) At 6850 yards, the course is quite short for the outstanding player.
The primary strengths are:
1) The course tests your ability to judge uphill and downhill constantly, much more than typical.
2) Enjoyable short game play around the greens. The greens have lots of slopes and lots of internal contours. The bunkers are deep and difficult, often several yards from the green's edge.
3) World class desert course conditioning, with perfect, deep green playing surfaces.
4) Most importantly, the course is unusually beautiful, a real piece of golf course art, with artfully constructed bunkers and waste areas, and wonderful use of existing rockpiles to frame greens. Furthermore, the course sits way above the Coachella Valley, so the golfer is treated to magnificent short range and long range views all day long.
It's a 7.
