The mainland ice caves of the Apostle Islands National Lakeshore reopened to visitors Saturday, following a temporary closure brought on by this week's winter storm, the St. Paul Pioneer Press reports.
The National Park Service closed access to the caves Thursday evening because of concerns that high winds could affect the safety of the icepack along the Lake Superior shoreline, which visitors must walk on to get to the caves. The park service said Saturday morning that the ice remained stable following the storm and visitors can once again see the caves.
The storm brought more than a foot of snow to parts of northern Wisconsin, and the park service advised visitors to prepare for very deep snow and cold winds. It'll be difficult to walk the mile or two to the caves, so visitors should plan to use cross-country skis or snowshoes until the path is packed down again, reports the Duluth News Tribune.
The park service opened access to the ice caves in mid-January for the first time since 2009. The caves have attracted national media attention this winter, and an estimated 50,000 visitors have made the trek to see the phenomena.
