Bighorn Medicine Wheel, Wyoming
Stone circles are usually shrouded in mystery. But, in northern Wyoming’s Bighorn National Forest, Bighorn Medicine Wheel goes one step further and is covered in snow throughout the winter months. Come summer, it melts away to reveal limestone rocks strewed in a wheel shape with spokes encased in a large circle.
Some experts have dated the mountaintop ruin to at least AD 1300, and it forms part of a chain of American Indian archaeological sites up to 7,000 years old. It’s believed that the pattern was used to predict astronomical events, like the Summer Solstice, for example, though the truth remains something of an enigma.
