Mike Cirba,
I'd be happy to accept an active role.
Neil,
Smith and Carr were fellow members and good friends of Crump's, intimately familiar with Pine Valley.
From about 1914 documentation regarding the 18th green appears from them.
Essentially they wrote that Crump was dissatisfied with the green, primarily due to its size and lack of character. In addition, Crump specifically wanted to challenge and/or punish the sliced approach into the green.
Crump initially conceptualized, designed, constructed and completed a mound to serve that purpose.
Evidently, after the hole was in play, he decided that a spine/ridge/roll would serve a more functional purpose than the mound.
General descriptions of Crump's intended feature are provided by Smith and Carr, some of them dated as early as 1914.
At the time of Crump's death in 1918 the mound remained in the green.
I believe, and TEPaul can confirm, that the 1921 Advisory Committee discussed or recommended the removal of the mound.
In or about 1926 the mound was removed, however, Crump's intended spine/ridge/roll was never installed.
The spine/ridge/roll was described in general terms, including where it should be in the green and where it should end at the back right section of the green.
# 18 was one of Crump's two favorite holes, the other being # 2.
With # 18 being the finishing hole, with such a large green, (over 11,000 sq/ft today, and probably much larger in 1914-1926) Crump determined that it needed challenge and character, two vital components on an 18th hole today. Yet, the green remains bland and unchallenging on the approach, recovery and putts.
My guess is that the feature may have been unpopular with John Arthur Brown. If so, there was no way that it would be restored during his tenure. His reign at PV approached 50 years, hence, by the 1970's it's doubtful if many or any members were aware of the history of the 18th green. That being the case, there would be no interest to restore the 18th green to reflect Crump's intent because few if any were aware of his intent.
My suggestion is to build an 11th hole on the short course, incorporating an interpretive rendition of Crump's spine/ridge/roll.
This field experiment could be adjusted based on observation, critical analysis and intelligent feedback. While it's possible to "get it right" the first time, the beauty of using the 11th hole on the short course is that it saves the 18th green from going through the trial and error period.
After a few years experience the club would have done their due diligience, prudent analysis and be adequately prepared to restore the 18th green to reflect Crump's intent.
In addition, it would make the 18th hole a far better hole, more challenging on the approach, recovery and putts, with a green full of character and interest.
