Stand on the bluff above Lake Michigan at Whistling Straits and the land seems to have been arguing with the water for centuries. The fescue leans in the wind, the sand breaks open in ragged hollows, and the lake stretches away like a northern sea. It is one of the great illusions in golf, because almost none of it was here before. These 560 acres near Sheboygan were flat ground, once a World War II military base and later an airfield. Everything that looks ancient was made. The dream belonged to Herb Kohler, who had already worked with Pete Dye on the two courses at Blackwolf Run a few miles away. What he asked for this time was audacious: a walking-only course "like Ballybunion" on the shore of a Great Lake, in an era when American design leaned toward containment mounds, water features, and carts. Dye called it a "once in a lifetime thing," and the land demanded nothing less. Millions of yards of earth were brought in, and sand came by the ton from a nearby farm. Dye's key idea was to push the shoreline bluffs back inland and use them to build false dunes. The U.S. Army Corps of Engineers, which had the final word, saw that the new beaches could stand up to the crashing waves and help stop the ongoing erosion, and it said yes. To push those bluffs back, the crews used the frigid winter months to drive heavy machinery out onto the frozen lake. There is something wonderful in that image: bulldozers on the ice, building a coastline that would pass for something far older. The course opened in 1998, and its design is as clever as its earthmoving. Dye stepped the ground so the inland holes sit above the lakefront ones, which gives every hole a stunning view and lets the whole place drain. The routing is a double figure eight along two miles of shore. Eight holes run directly beside the lake, four heading north to south and four south to north, and they come in pairs, so the round alternates between two holes on the water and two above it. You are always leaving the lake and always about to meet it again. Then there are the bunkers. Before the 2010 PGA Championship, Ron Whitten spent two mornings counting and arrived at 967, with 102 on the 8th hole alone. Walk the fescue and you might easily believe there are more than a thousand. The effect is less a set of hazards than a weather system of sand. The 17th holds the course's best family story. Alice Dye told Pete the hole wasn't hard enough, that there needed to be "a chance of making double bogey." Kohler wanted the green pushed atop a tall nearby mound. Alice wanted a pond between green and lake. Pete ignored them both and built a big fronting mound that hides half the putting surface from the championship tees, choosing deception over physical danger. Alice sketched all three ideas and titled them "Herb Said," "Alice Said," and "Pete Did." The framed drawing hangs in the clubhouse bar. Championships followed. Vijay Singh won the 2004 PGA Championship here in a playoff. In 2010 Martin Kaymer beat Bubba Watson in another playoff for his first major, becoming only the second German to win one after Bernhard Langer. Dustin Johnson should have been in that playoff too, but he grounded his club in a bunker and took a two-shot penalty. In 2015 Jason Day won his first major by three over Jordan Spieth at a record 20 under par. By the time the Ryder Cup arrived in 2021, the made-up dunes had become a modern classic, a landscape invented so convincingly that the lake seems to have always known it.
