Montana, known as “Big Sky Country”, is a land of high mountains, broad plains, and big rivers. Glacier National Park, in the northwest, encompasses more than one million acres filled with wildlife, dense forests, jagged peaks, deep lakes and glacier-carved valleys. The vast areas of National Forest land, including the renowned Bob Marshall Wilderness, are popular for all outdoor activities. This map card is part of National Geographic’s TOPO!
