Iron horse was built on Grier Ranch that was used to pasture horses and graze cattle.
Quoting John Strawn in Chapter 6 beginning. "I spent a lot the the summer of 1988 walking the grounds of Ironhorse, a copy of Art Hills's routing plan tucked under my arm, trying to discover what in the site might have inspired the shape or encouraged the features he planned for the golf course. What I saw mostly was an accumulated tension between Ironhorse's native south Florida flatness, its topographical ineffability, and the contours proposed by Hills's design. At Ironhorse, unlike a site with geographically derived shapes, the cavas was blank. Laying it out was a pure problem of design. Every bump, every swale, every mound and bunker grew first on a drafting table in Toledo, Ohio. Ironhorse had no gullies to ford, or hills to level, just a flat receptive surface awaiting what Mike Dasher called the "sculpture by addition" that golf architects perform in south Florida. Ironhorse had lots of vegetation, but no movement in the ground."
Naturally when you do "sculpture by addition" you create wetlands (ponds) by subtraction.
I think Mr. Wind used a bit of hyperbole.
