Ok, as promised in my post, I looked at the photo again. It is dated 7/30/23, right around the time Congressional opened. The aerial says "US Army Air Service" Bolling Field, Washington. It is an aerial of the entire property (at the time) taken by a plane heading roughly north, with Persimmon Tree Road clear in the bottom of the picture, and what is now Bradley Boulevard to the left (West) in the picture. It is interesting! No yardages are given for the holes, but the layout is shown with dashed white lines an "Hole X" designations. Bunkers, tees, greensites, and water features can be discerned from the picture.
What I did in this email is use my current Congressional yardage book to compare to the aerial. The Gold Course half of the yardage book also mentions "the original Congressional layout on the inner nine holes" which makes me believe that a lot of the current Gold Course was part of the second nine of the original Blue Course.
The first hole was a par 6 (!) Here's one of Emmet's "quirks". It appeared that there were bunkers flanking the drive zone which cut into the fairway, as well as a cross bunker about 2/3 of the way to the green (Emmet used crossbunkering extensively to my understanding). I know this was a par 6 because another picture near the pro shop is from the '20s or '30s, of a grader being operated, with a caption reading "...the par 6 first hole".
It's interesting to note that holes 1 and 2 today add up to a little over 600 yards. The original first hole played in roughly the same direction as today's first hole. (I'm playing the Blue course tomorrow (Monday, 5/3), so I will be able to get a better idea of the design of the greens, etc firsthand). The original second hole looked, from the picture, to cover the same ground that today's 5th hole occupies. Same fairway shape (big right to left sweep, however I couldn't discern any significant bunkering, with the exception of two greenside which appeared to be "C" and "reverse C" on either side of the green. There are some mounds along the right side of the fairway on 5 which might be an original Emmet feature as well.
The original 3rd hole looked to be a short/medium par 3, playing from the left of (original) 2 green away from Bradley Blvd. to somewhere between (current) 8 fairway and (current) 8 tee box.
The original 4th looked to play from the left of (original) 3 green to somwhere near the current 7th green. (away from Bradley Blvd.)
The original 5th went in the opposite direction over the same ground as the current 9th, and the original 5th green may have occupied what is now 9th teebox, or possibly today's 8th green. (towards Bradley Blvd.)
The original 6th looked to be a long par 3 or short par 4, playing up the current 4th fairway.
In my yardage book, there appears to be a greensite to the right of today's 4th teebox--might be an original greensite. I'll look at this tomorrow.
The original 7th appeared to be a medium par 4, playing towards Bradley Blvd.
The original 8th paralleled the first, and appeared to feature 2 cross bunkers in the fairway, one and then another closer to the green.
The original 9th looked to be a par 3, playing back towards the clubhouse. We have a few practice greens, and I wonder if one was the original 9th green. It features several tiers and bunkers, but these could have been added or modified anytime.
So it appears that RTJ used the original 1st and 2nd holes, and maybe parts of others, to create the current first nine of the Congressional Blue course.
The original 10th looked to be a LONG par 5 (or another par 6?) playing away from the clubhouse parallel to, but running in the opposite direction, as today's 17th on the Gold Course. It appears that the current 1st teebox of Gold may have been the original 10th teebox, from the picture and my yardage book. The green looks to be in the same general location as the current 2nd green on the Gold Course.
The original 11th looks to be the same hole as the current 3rd on the Gold Course. Same direction of play, appears the same length (at my best guess). There is an old picture of a par 3 in the card room of the locker room from before 1950 (from the appearance of the picture), could be the exact original hole. The bunkering looks to be the same in the picture as is in my current yardage book.
The original 12th looks to occupy the same general ground as the current 4th of the Gold Course. The fairway looks to have changed a bit--different shape to it. Might be the same green.
The original 13th looks to be today's 5th of Gold. From the aerial, both look about the same general distance. Again, might be the same green.
The original 14th looks to occupy the same general land as today's 15th of Gold, and direction of play is the same. Again, maybe the same green.
The original 15th looks to occupy the same land as today's 16th of Gold, and again, direction of play is the same. Again, could be same green.
The original 16th was a short par 3 to a green ringed by bunkers. Your aerial shows this hole in the top center of the photo--look for a small green ringed with 3 bunkers. This hole is still in existence today, but it is not used by either course. You can see it from Persimmon Tree Rd.
The original 17th of Blue looks to occupy the same general ground as today's 17th of Gold, and again, direction of play is the same.
The original 18th of Blue looks to be a par 3 or short par 4, and plays in the same general direction as today's 18th of Gold. A three-tiered practice green sits directly above the current 18th green of Gold. I think this could be the original 18th green, but it's only a guess.
