This Saturday, the breathtaking ice caves at Apostle Islands National Lakeshore in Wisconsin will open for the first time this season. The ice caves are an always changing phenomenon — the formations change from chamber to chamber and from day to day. The result is a fairyland of needlelike icicles. Visiting the ice caves requires at least a 2 mile hike across Lake Superior, and present conditions might make it a challenging trek. For up-to-date info on the ice caves, visit ww.nps.gov/apis or call the Ice Line at (715) 779-3397 – extension 3. National Park Service photo.
