- The Apostle Islands National Lakeshore needed to call in reinforcements to handle the thousands of people visiting the area.
They're coming to see the majestic beauty of ice caves along the south shore of Lake Superior.
Even on Monday, the ice caves drew 18-hundred people throughout the day.
It's been five years since the ice has been thick enough for hikers to safely reach the caves.
Chief ranger Chris Smith says this past Saturday was the busiest yet this winter, with 11-thousand people making the trek to the caves.
Smith says five other national parks have sent staff to help, along with local sheriff's offices, the U.S. Coast Guard and Border Patrol.
