CAIRNS Director Interviewed for Medicine Knoll Video

South Dakota Public Broadcasting’s associate producer, Michael Zimny, traveled from Rapid City to Wingsprings to interview the CAIRNS director for a video feature he is developing. The feature is about a snake effigy that was created by arranging rocks and stones in an undulating outline of a rattlesnake that is over 300 feet long. It is located on a long flat butte - Medicine Knoll - east of Pierre, South Dakota. The CAIRNS director had surveyed this and a handful of other eastern South Dakota “boulder mosaics” over 30 years ago as a graduate course project.
