 I am standing beside the Bighorn Medicine Wheel, located in the Bighorn Mountains, 30 miles east of Lovell, Wyoming. This ancient circular pattern of rocks was created approximately 700 years ago and is one of many medicine wheels found throughout North America. This historical remnant is named for its bicycle wheel shape. Individual stones and a number of rock carons form the 80-foot wide rim of the wheel as 28 spokes radiate out from a prominent central caron. Historians and archaeologists believe the wheel and the surrounding landscapes were used for ceremonial and traditional uses by a great number of prehistoric peoples. There is also evidence to suggest the rock arrangements of the wheel served an astrological purpose, pinpointing various days of the calendar year such as the summer solstice as well as corresponding with the lunar month. Still today, the wheel holds spiritual and ritual significance for many American Indian tribes. Visitors are also asked to respect the sacred nature of the site by leaving rocks and prayer offerings undisturbed. The next time you're in the Bighorns, consider a visit to the Bighorn Medicine Wheel to visit and explore what has been called one of the largest and most elaborate Indian structures of its type.
