The Daily Croissant

"A mysterious pattern of stones sits at the summit of Medicine Mountain, nearly 10,000 feet above the Bighorn Range in Wyoming. Covered by heavy snows for most of the year, the stone configuration reveals itself and its purpose only in the summer months.  

The stones are arranged in the shape of a wheel, 80 feet across and with 28 spokes emanating from a central cairn. The cairn, a ring-shaped pile of rocks, is large enough to sit in and is surrounded by six others that lie along the wheel’s circumference."
