Bunker Construction - MacRaynor?

[JJShanley]

The threads on bunker construction and design on British and Irish links courses got me thinking: how did MacRaynor build their high faced bunkers? 


Examples
Camargo


From GolfNow.com


NGLA


From The Itinerant Golfer


Did they build sod, then cover with turf?  or just build a smooth slope that they covered with turf? 


I didn't like the bunkers at Camargo when I first saw them, but they grew on me over the course of the round.  I think the flat entry in contrast to the slope put me off, given that I hadn't seen anything like that before.


EDITED FOR SIZE OF PHOTOGRAPH.

JJ,
 
In many, if not most cases, they elevated the green.
 
If you walk NGLA backwards, starting from behind the 18th green, you'll be amazed at how constructed and elevated the greens are.
 
This allows for deeper bunkers.
 
But, you left out Charles (Steamshovel) Banks, a MacRaynor desciple.

Thanks, Pat. 


I had picked that picture randomly from a Google Image search, but I wonder now: How do you build such a bunker in the early-twentieth century?  Did MacRaynor build up that green?  If so, how did they go "back down" to build the bunker, without the whole thing giving way?  Would such a Road Hole bunker prove far more difficult to build than say the large, deep bunker to the right of that green that has an easier (it seems from photographs) entry? 


Someone may/will have a simple answer, but I'd love to see a photograph of the construction, or read an explanation, either specific to NGLA or to MacRaybanks courses in general.
