I reckon I am in the Paul Camp. This type of bunker is akin to visiting the freak show tent at the circus. As I am on the straight and narrow campaign of reducing the use of sand I don't see how I can can for this sort of thing. That said, at least its a bit different and for this reason alone I would take it over the endlessly bland and pointless pits that are built in the name of architectural progress.

Sean - My memory might be askew, but... #7 at Huntercombe - does it not have volcano type bunkers? I can't find a photo anywhere, but I see this type of bunker in my mind's eye.
Tony Nysse - The Dye Course at Colleton River Plantation definitely uses this type of bunker in several places... as does Dye's course at Hampton Hall. I'm not positive, but I believe this Volcano-type bunker can also be found at the new Heron Point course that Dye built over the old Sea Marsh property.
Dye uses this feature often... and not just recently as this bunker can be found at Prestwick CC in Surfside Beach, SC which was built in 1989.
I'm confident there used to be a volcano bunker on the par-5 11th hole at The Ocean Course at Kiawah. As I remember, it protected the direct line to the green on one's second shot or forced a layup to the right. I don't believe it is still there, however. Perhaps Mike Vegas can comment.
