Icicles line sandstone walls of the mainland sea caves at Apostle Islands National Lakeshore, Lake Superior.
The mainland sea caves are sandstone formations along Lake Superior within Apostle Islands National Lakeshore in Wisconsin. In winter, when the lake ice is stable, visitors can walk onto the ice to view the caves' frozen icicle formations from the shoreline. The National Park Service manages access to the caves and issues advisories based on ice conditions each season.

The mainland sea caves are located along the Lake Superior shoreline within Apostle Islands National Lakeshore near Cornucopia, Wisconsin. The caves form in sandstone eroded by wave action, and in winter, meltwater freezes into icicles and ice formations along the cave walls and ceilings.

Ice formations in a cave along the shore of Lake Superior at Apostle Islands National Lakeshore, Wisconsin, February 2014.
During the winter of 2014, the Apostle Islands National Lakeshore in Wisconsin experienced a period of extreme cold, leading to the formation of spectacular ice caves along the mainland shore. These natural formations are created when waves freeze onto the sandstone cliffs, and dripping water from above forms icicles and ice curtains. The caves are a temporary natural phenomenon, accessible only when Lake Superior freezes over sufficiently to allow safe passage. Their ephemeral beauty draws visitors who brave the cold to witness these unique geological structures before they melt with the spring thaw.
