As a young girl growing up in central North Dakota, Linda Olson paid attention to the terrain. Rocks and prairie grass were part of the everyday landscape. Olson’s love of rock art became her primary research focus after taking a course at the University of North Dakota. Since then, she has traveled the United States and beyond, pursuing her passion for ancient rock art in canyons, caves, deserts – wherever petroglyphs are found. Olson has spent the last 20 years providing a definitive, artistic record of petroglyphs created by people on rock surfaces and investigating sites, primarily in Wyoming, New Mexico, Montana and Colorado. In May 2012, she found herself in Perú, a land of bold colors and ancient architecture, and took advantage of the opportunity to investigate one of Perú’s most famous rock art sites, the Nazca Lines.
