TEPaul,
Many early mounds were simply function over form.
Debris piles, usually offset, that served a vital function and kept construction costs down.
Tillinghast's dolomites are as about as unnatural as you can get at Somerset Hills, yet few, if any, ever criticize them as unnatural looking, or out of place or out of context with the surrounding holes and land.
Many clubs, not understanding their intent, put plantings, shrubs, flowers and trees on top of, or blocking agents to hide these neat features. My club in NJ had many of these debris mounds, in different shapes, elevations and dimensions.
Almost universally, they've been planted and have lost their unique contribution to the feel of the golf course, and the architecture.
There is an early aerial of the golf course which shows the major mounds as a dominant feature on the golf course, seperating a dogleg hole from a relatively straight one, hence the architect incorporated a debris mound into an important component on both holes.
In addition, many greens have elevated wings at the rear corners, and I've always been curious to see the results of a soil probe in these areas to see if they served a dual purpose.
Today, large mounds can serve a valueable purpose.
They can screen off eyesores, serve as sound barriers, safety barriers, for drainage and be used to bury debris that would otherwise cost a fortune to dispose of off property.
I think you have to analyze them in the context of their purpose.
