Waterfalls are now flowing thunderously into streams and rivers and the ice has mostly thawed around Munising Bay. Higher temperatures are projected throughout the week, and the welcome signs on the eastern and western ends of Munising were switched from images of ice caves and snowmobiling to summertime scenes of the Pictured Rocks National Lakeshore. Although remnants of snow piles still linger throughout the area, there are sure signs that warmer days are on the horizon.
