Years ago, someone posted a picture of the topo map of the Eden (pre-renovation) which was instructive. I copied it, but can't seem to paste it.
I was never impressed with the Eden, or shall I say purported copies of the Eden, because HHW wrote that the paired hazards were the key - avoid the deep Strath bunker too far left, and you get in the Hill bunker.
In reality, it is the ground contour that make the original, not the hazards. The crumpled ground in front made it plenty hard to run up reliably and the very steep back to front made it hard to putt from beyond the hole. With modern standard 2% greens, it is really a more straightforward carry the bunker or don't shot, resulting in a longer putt.
