ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by Keith Ladzinski @ladzinski Dramatic skies stretch across the blue waters of Lake Michigan and the expansive shoreline of Sleeping Bear Dunes National Lakeshore. This beautiful wall cloud slammed the coastline shortly after I shot this, showering the area with torrential rain that had me running back to the car—a small price to pay to witness such a beautiful storm!
