Sitting at the base of cliffs usually populated by mountain goats along the Continental Divide Trail between St. Mary and Two Medicine in Glacier, Morning Star Lake has a backcountry campground in the forest a short walk from the lakeshore—which means that backpackers camping there have a chance to see how the sunrise and sunset transform that landscape. With luck, you catch a calm evening or morning, when the lake’s surface reflects the forest and distant peaks like a mirror.
