This new Express Mail stamp depicts the winter beauty of the Grand Island Ice Caves in Lake Superior, on Michigan’s Upper Peninsula. Grand Island is marked by massive sandstone bluffs that are especially dramatic in winter when lake water seeps into the crevices and caverns, forming magnificent ice curtains and icicles that hang like stalactites from ceilings. The stamp art features a colorful illustration of how one of these ever-changing ice caves might appear from the inside looking out toward the west at sunset.
Viewing ice caves and ice formations has become a popular winter activity at Pictured Rocks National Lakeshore and the surrounding area. The ice generally begins to form by mid-December and remains until early April, forming columns of blue, white, or yellow ice 20-50 feet high.
