3-18-14 ice caves close

BAYFIELD, Wis. (AP) — The popular ice caves on Lake Superior near the Apostle Islands are now closed, concluding an unprecedented wave of tourism and exploration. The National Park Service says the caves along Lake Superior were closed just after midnight Monday. Officials say 138,000 people visited the caves this winter, dwarfing the 12,700 people who visited in 2009, the last time the lake froze enough to make the caves reachable by foot.
