American Dunes opened in 2021 and is a total reinvention of an existing course. In this case, Nicklaus took a wooded, decades-old design and nearly cleansed it of trees, opening up views across a lunar surface of heaving sandscapes that separate the holes. Extreme topographical variety has replaced a succession of narrow, repetitive golf holes with circular greens and players now face enticing tee shots that must skirt sand barrens and putting surfaces shaped in all manner of size and pitch. Created by Lt. Col. Dan Rooney, whose family owns the property, much of the course's proceeds are donated to Folds of Honor, a charitable foundation that supports injured veterans, their families, and awards scholarships to children of wounded or killed military men and women.
