One newer course that I can think of that has such a hole is the sixth at the Gauntlet at St. James in Southport, NC. It's a 255-yard par 4 and it's very tempting to go for the green. If you manage to hit it and stick it, more power to you. If you miss short, you've got a bunker. If you miss long, right, or left, you'll be well below the surface of the green. I don't recall exactly how far it drops off, but I think it's at least 10 feet. The course was designed by P.B. Dye and at a 143 slope it's about the most difficult course in the area. Perhaps there are a couple in Myrtle beach with higher slopes, but not many.
