If you think rock art is Velvet Elvis or weird album covers you need a little educating from Linda Olson, Professor of Studio Arts at Minot State University. I could not believe how fast the time went on this subject.
Linda tells us about some local (ND rock) at and more. BTW the proper names for rock art are petroglyph (art carved into rock), pictograph (art painted unto rock), and petroform or geoglyph (art made from rock). We also talk about fiber arts. Again, just to clarify, fiber arts involve fiber... not fiber optics.
