Hole 18 · Par 4 · 494 yds
This tour was mapped on aerial imagery from 2 August 2019, before Tyler Rae's 2024–25 restoration rebuilt the bunkers and returned several greens to their original shapes, so bunker and green outlines on the course today differ from the images. The par and yardage shown for each hole are from today’s card.
The longest par 4, home over a pair of ponds
The 494-yard 18th from the ONE tees is the longest par 4 on the course and stroke index 4. The mapped tee is about 25 yards ahead of the back tee, so distances are measured to the green. The hole turns about 26 degrees left roughly 210 yards short of the green, with trees down the right side of the fairway. Two ponds divided by a cart path cross the approach between about 45 and 90 yards short of the middle of the green, and the clubhouse stands behind it. The Chicago District Golf Association reported that Rae split the pond here into two in 2024-25 to restore Ross's layout.
