TEPaul,
Actually, I've been into mounds for many years, dating back to the 60's.
A course that I'm very familiar with, circa 1927, is replete with debris mounds, interestingly dispersed around the golf course.
I find the use of mounds by the old timers fascinating.
As you know, those guys were highly efficient and frugal, as were the clubs when they were coming into existance.
Carting debris off site was expensive.
They figured out how to retain debris as an architectural feature close to the acquisition area.
If necessity is the mother of invention, these guys understood that and converted a negative into a positive in a highly efficient manner.
What I find fascinating is their integration with drainage patterns, the adding of tecture to the golf course and the injection of a form alien to the land, yet functional in the play of the game.
Perhaps my interest in them was fueled at an early age by going to the movies and seeing Jane Russell
