WANT TO OBSERVE WIND CAVE’S LARGE BISON AND ELK HERDS? SEARCH AND LISTEN FOR “BUGLING,” THE ELK’S CALL, IN EARLY MORNING AND LATE EVENING. 5. WIND CAVE NATIONAL PARK Deep beneath the vast expanse of the golden, windswept prairie in western South Dakota is the sixth-longest cave in the world and one of the most complex cave systems, a subterranean realm of maze-like passageways, water-carved rock formations and delicate mineral growths. Wind Cave is considered a sacred place for Native Americans and, in 1903, President Theodore Roosevelt signed the bill that created Wind Cave National Park. This park also features more than 30 miles of hiking trails above ground, offering ample opportunities to spot bison, elk and other wildlife roaming freely. More on page 75.
