In fact, there used to be two bunkers along the right hand side on No. 1 (the second being located not too far over 17-Mile Dr.), both of which have been removed.
In addition to the short fairway bunker on 14, another which was located in front of the trees along the right hand side of No. 14 fairway (right where the fairway begins to pinch in) has also been removed.
At No. 2, two greenside bunkers originally guarded the left hand side have been turned into three, but look to have maintained the same shape.
The third hole seems to have lost three bunkers, one directly behind the green, and two that were located approximately halfway between the present greenside bunkers and where the cartpath bisects the fairway. At first glance they seem superfluous, but Shackelford notes that they were constructed by Mackenzie to add difficulty in judging distances. Further, it does make the hole look more fearsome - the Mackenzie dictum of look hard, play easy.
The fairway bunkering at the turning point of the fifth hole appears to have been scaled down significantly.
The bunker behind the green at six, which used to bleed out of the enormous sand dune looks like it has been grassed over, and the large right hand side fairway bunker has been dramatically parred down in size.
At No. 10, the large fairway bunker immediately off the tee has been reduced into two smaller bunkers, and the furthest right hand side bunker in the landing zone has been eliminated.
In addition to the bunkers removed from amidst the trees at No. 17, the green has lost two bunkers which hugged the front right & left portions of the green and extended down to the rocky coast line.
Overall, it looks like much of the bunkering has lost some of it's expansiveness, and the hazards that had evolved naturally out of the sand dunes have over time, been turfed.
