Officials closed the area Thursday night because of the strong winter storm and uncertainty how it would affect ice conditions on the lake. It was reopened over the weekend. WDIO-TV says rangers recommended snowshoes or cross country skis because of the deep snow and high wind.
More than 60,000 people have visited the ice caves since Jan. 15, which is more the 1/3 of their average yearly visitation. Rangers have gotten some help handling the crowds from other national parks, the sheriff's office, U.S. Coast Guard and Border Patrol.
