Although I have not seen a 'Steamshovel' Banks or Barton's work, I assume the style of green and surrounds depicted specially in the second picture is of the Macdonald and Raynor school or genre. I heard from Bruce Hepner that Leonard MacCumber also did some surveying work for Raynor. But, none of their biographies are in synch with your description, Jim. The only other archie I know who did green designs of squarish dimensions and steep sloped turf faced engulfing bunkers to flatish sand like your second pic, was Langford. The second picture looks quite a bit like the 3rd at CC of Charleston, although I am sure it is not. Of course that was Raynor.
If you are saying the first picture is of the result of a remodelling of the course from where the second pic was taken, I'd say that the bunker openings have been given that "upholstered" look that was so objectionalble when we had the big "Merion" discussion. The first also has some resemblance to Yeamans Hall, but YH is more rustic and Doak and crew gave the bunkers a more sharp edged outer lip. Besides, the first pic looks too lush to be YH.
I'm anxious for you to tell us who and where the course you have posted is...
