Medicine Wheel Passage

The Medicine Wheel Passage follows US Highway 14A for about 27 miles between the Big Horn Basin and the junction with US Highway 14 (the Bighorn Scenic Byway) at Burgess Junction high in the Big Horn Mountains. This is a journey from the wide open high altitude desert of the Big Horn Basin up into the pines and then spruces and aspen of the Bighorn National Forest in the northern Big Horn Mountains. Along the way you'll pass the turnout and trail to the Medicine Wheel National Historic Landmark: this is a precolumbian rock structure near the summit of Medicine Mountain. The circular rim is about 25 yeards in diameter and has 28 spokes running to it from the center rock cairn. There are six more rock cairns of varying smaller sizes built near or on the circular stone rim. A 1972 investigation of the site by Astronomer John Eddy determined that various pairs of the cairns were used to determine/predict certain astronomical events, like the summer solstice. And the layout was very accurate for the time period between 1200 CE and 1700 CE.
