10. Bighorn Medicine Wheel (Wyoming)
Perched atop Medicine Mountain in Wyoming’s Bighorn National Forest, the Bighorn Medicine Wheel is an 80-foot-diameter stone structure constructed by Plains cultures, possibly the Crow, Cheyenne, or Shoshone, between 1200 and 1700 AD. The wheel features 28 spokes radiating from a central cairn, with six additional cairns positioned around its perimeter. The site is aligned with celestial events, suggesting its use for ceremonial and astronomical purposes. Accessible via a marked gravel road from U.S. Highway 14A, the wheel is located at an elevation of approximately 9,640 feet. (fs.usda.gov)
