Bighorn Lambs, Badlands National Park, South DakotaA group of bighorn lambs showing why it can be hard to spot a group of bighorn lambs. These guys were playing amidst the eroded buttes in Badlands National Park. In addition to their great camouflage, they also are well adapted to the steep, almost vertical landscapes they live in.
