David Kidd began building a second 18 at Wisconsin’s Sand Valley Resort just before Coore and Crenshaw had completed their 18, which would be named Golf Digest’s Best New Course of 2017. Kidd was intent on topping their work, so he gave his meandering layout enormous fairways, big accessible greens and visually-unique hillsides of exposed sand, “mammoth dunes” that became the course moniker. “This could be the best course I and my team have yet created,” Kidd wrote in late 2017. “We can’t wait for the critics to decide if they agree.” They were disappointed with results of Golf Digest’s 2018 Best New Course survey, which placed Mammoth Dunes second behind Streamsong (Black). But balloting for Golf Digest’s 100 Greatest continued for an additional month after the close of Best New, and additional evaluations pushed Mammoth Dunes ahead of Streamsong (Black), which is now ranked No. 169.
