OK, the last three photos Kalen posted in reply #30 are of holes 12 & 13.
When I did the routing of the back nine, I thought either #12 or #14 would be the star of the bunch. The twelfth featured a second shot down between two massive sugar maples, to a green set on the shoulder of a hill falling from left to right, with #10 fairway just to the left. I built a green that had a higher left tier and a lower right tier, and it angled just slightly to the left, back behind the big maple at the front left of the green. It was a very difficult second shot, although some of the difficulty was that the tree was so big they were always losing the grass underneath it, so if you missed left you had to scuffle a shot under the tree from a bare lie.
I mentioned above that #12 fairway had the only real earthwork of any fairway on the course. Originally, the fairway went out flat about 200 yards and then dropped to a lower level ... so you could not have seen players ahead of you in the landing area. To fix that, we made a big "U" shaped cut across the fairway from right to left, and pushed up the material into a big mound on the left, and then built a sprawling fairway bunker into it. My younger brother worked on the crew for a couple of months to help me out, and it was he who named the bunker "Bullwinkle" because he thought the shape of it looked like moose horns.
As I just said, I thought #12 or #14 would be the best hole on the course; #13 was just the hole I had to build to connect them, although I had high hopes for the green, which was set on the saddle between two small hills. It was the first green we actually built, and turned out to be one of the best greens I ever built ... the front right and back left sections were lower, and the front left and back right sections worked up into the hills. The really fun hole location was the back left. Instead of playing straight at it, and going out the back, you could play up toward the back right of the green and there was enough tilt that the ball would turn left and come back down the slope to nestle close to the flag. [I only ever saw one person hit that shot on the approach, but it was often done by players chipping and putting from the right who knew the green.]
The fairway was tilted quite sharply from right to left; it went over a crown about 220-230 yards from the back tee, leaving nearly everyone with a downhill / sidehill lie for the approach. I think the tilt was 6 or 8 percent from the crown in three directions; most anyone now would have softened it, but it worked fine without it, though it did exaggerate the benefit of being able to carry the ball a certain distance. Also, from the back tee on top of the ridge, the trees on the left made it hard to aim left if you were a fader, and this got worse over the years, to the point that they couldn't use the back left tee at all the last few years the course was open. This was also the hole where the natural ferns provided a great hazard on the right when the course first opened, with a few small trees spotted here and there, but as the pines got bigger the right side became too thick and you just couldn't afford to miss it there, a problem which was exacerbated by the trees off the tee.
In all, I still consider #13 at High Pointe one of the best par-4 holes I ever built. I don't know if it will really be possible to build a green like it on another course, but I will certainly keep an eye out for the right opportunity.
