jkinney - Thanks much for the detailed description. The satellite images from Google maps show just that without any idea of the elevation differences. It sounds like a perfect place to hit a few short irons to warm up for a truly unique round of golf! The closest I can claim to seeing NGLA was when my dad took my whole family on a road trip from Ohio to Long Island immediately after seeing Shinnecock on TV at the '86 Open....just to pull up the class Stanford White clubhouse after 10pm and deny my request to take the "Home of the 1986 U.S. Open" sign in the drive! Disclaimer: I was 14.
Bill - That is fascinating...yes, you can see them very clearly on the 1954 aerial I posted the link to. In the '60, the two of those greens, Short & Eden, seem to be in use while the Redan looks to have been abandoned or washed out (the back half is gone). By '69, there is narry a trace!
Could this have been a source of inspiration to Fazio and/or PV with their short course...building greensites based on shots to be encountered during the round? It even looks like there where infinite places (within a finite area, of course) from where to approach these greens, another important characteristic at PV's short course.
