From the article:

“People have written about many impacts in different parts of the world based on the presence of spherules. "It may well have taken multiple concurrent impacts to bring about the extensive environmental changes of the Younger Dryas," says Sharma. "However, to date no impact craters have been found, and our research will help track one of them down."”

Maybe the impact crater is underneath one of the Great Lakes and now covered in sediment.
