Peering through a sea cave at Apostle Islands National Lakeshore, and you’re given a secret glimpse of the world. Located near the southwest tip of Lake Superior – the largest and most pristine of the Great Lakes – Apostle Islands National Lakeshore is comprised of 21 islands and 13 miles of Wisconsin shoreline. The colorful Precambrian sandstone has eroded into fascinating cliff formations and the park’s waters offer sailing, power boating, sea kayaking, fishing and scuba diving. This photo captures a view from a little cove on Stockton Island that came down during powerful breaking waves in 2017. Photo by Michael DeWitt (www.sharetheexperience.org).
