GWEN IFILL: And finally to our NewsHour Shares of the day, something that caught our eye that might be of interest to you, too.
Tonight: The wicked winter that struck again today in at least 20 states has also left something in its wake quite beautiful, access to a rare natural spectacle in Bayfield, Wisconsin.
Last weekend, nearly 12,000 sightseers at Apostle Islands National Lakeshore put on their parkas, strapped on their cleats and skates and set out across a frozen Lake Superior, their goal, to witness dramatic ice-covered sea caves in and the sandstone cliffs lining the Great Lake.
Accessible by boat in warmer months, the caves can only be reached on foot, when winter conditions create ice thick and stable enough to bear the weight of visitors. It’s a phenomenon that’s only happened three times since 2009. Still, once there, guests are privy to breathtaking views of icicles, ice crystals and even curtains of ice that appear to flow from the cave walls.
JUDY WOODRUFF: Beautiful.
