Near Viking, on the top of a hill, at the highest point for miles around, stand the only Ribstones in Alberta that have not been moved since ancient times. Ribstones, also known as Boulder Petroglyphs, are two large stones carved in the shape of an animal's rib cage. These ancient monuments have remained in place just a few kilometers from Viking, Alberta for thousands of years. Historically, the native people of the plains were dependent on the buffalo. They revered the spirit of Old Man Buffalo, expressing their prayers and gratitude at the Ribstone shrines.
