Tom,
This hole, in addition to holes 10-12 were built in 1922 in preparation for the 1924 Amateur. These were designed by Flynn and surely with oversight by Hugh Wilson, who was to die in the beginning of 1925 after being chronically ill for many years. They continued to refine, along with Valentine, the course, including the bunkering through the mid 1930s up to the 1934 Open. A few minor changes were implemented afterwards.
There were significant changes to the course between its opening and the 1916 Amateur. Even if the holes were conceptually maintained, numerous changes to the bunkering were done.
I'll try to post photos of the 1930 Amateur, but I don't recall differences made in 1925 or 1926.
"One look at the dopey trees behind your photo of today's 13th green demonstrates this."
Sean,
Please do not jump to conclusions. The trees are rarely in play (though I've overshot the green into them on occasion) and serve a purpose that you are not aware of. Prior to the famous first hole being altered for the 1930 Amateur, the tee was located near the clubhouse near the tree to the right of the pointed roof. Flynn redesigned the hole for the 1930 Amateur moving the tee to the other side of the clubhouse creating a fabulous dogleg right rather than the former dogleg left to a different green site. The entry road to the clubhouse was moved from the side of the current 1st and14th tees alongside the current 13th hole around the clubhouse which was directly in view from behind this green. The trees hide the drive into the clubhouse. The trees aren't at all "dopey."
"Where do you stand on the issue of restoration to fulfill archie intent VS restoration to carry archie themes forward if not in exact (or near enough given circumstances) detail?"
I am much closer to following the original intent. As someone that has written dozens of architectural evolution reports (following the model that Tom Paul established), I like to see them used to restore golf courses. Sometimes it doesn't make sense. But this can only be concluded when a careful and exhaustive study has been made. There are times I believe that evolution of a golf course, as a result of natural causes or the result of play, should be maintained. I am not dogmatic either way. If there is improvement in a golf course that enhances the play for modern players with modern equipment, I don't think there's a problem with going with the flow. But it has to be characterized as such. The cost of taking down evolutionary sand splash, correcting green contours, etc. adds greatly to the cost of a project and removes a natural defense of the golf course built up over the years from play. I kind of think that is an interesting evolution. It doesn't always make sense. In the case of the holes at Merion, I am convinced the right decision was made. It is fun to have a delay in seeing how the ball ends up and it requires a much more precise shot. I have to take the dog out in the rain---I'll try to address this further later.
