Blue wildebeest
This species of wildebeest seems to have evolved around 2.5 million years ago. The black wildebeest is believed to have diverged from the blue wildebeest to become a distinct species around a million years ago, in the mid- to late Pleistocene. Fossil evidence suggests that blue wildebeest were quite common in the Cradle of Humankind in the past. Apart from eastern Africa, fossils are commonly found in Elandsfontein, Cornelia, and Florisbad.
Black Elk Wilderness
Black Elk Peak, which at 7,242 feet (2,207 m) is the tallest mountain in South Dakota, is located in the wilderness, and one can see into four different states from the summit. Craggy peaks and rocky slopes mixed with ponderosa pine, spruce and fir trees make for a varied ecosystem. Mountain goats and bighorn sheep inhabit the more rugged mountain slopes, while mule deer, whitetail deer, and elk are more common in the forested valleys. A sizeable population of hawks and falcons also inhabit the wilderness.
