Product Details
By Geri Schrab & Robert Boszhardt

Watercolor artist Geri Schrab and archeologist Robert "Ernie” Boszhardt team up to interpret the hidden history and heritage painted in American Indian rock art—the ancient petroglyphs and pictographs—found in the Upper Midwest. With an eye toward preservation, Schrab and Boszhardt take you with them as they research, document, and interpret the petroglyphs and pictographs made in past millennia. In addition to publicly accessible sites such as Wisconsin’s Roche-A-Cri State Park and Minnesota’s Jeffers Petroglyphs, Hidden Thunder covers the artistic treasures found at several remote and inaccessible rock art sites in the Upper Midwest—revealing the ancient stories through words, full-color photographs, and Schrab’s watercolor renditions. Offering the dual perspectives of scientist and artist, Boszhardt shares the facts that archaeologists have been able to establish about these important artifacts of our early history, while Schrab offers the artist’s experience, describing her emotional and creative response upon encountering and painting these sites.

Viewpoints by members of the Menominee, Ho-Chunk, Ojibwe, and other Native nations offer additional insight on the historic and cultural significance of these sites. Together these myriad voices reveal layers of meaning and cultural context that emphasize why these fragile resources—often marred by human graffiti and mishandling or damage from the elements—need to be preserved.

Geri Schrab is an award-winning watercolor artist whose sole artistic focus is American Indian rock art sites. She has twenty years of experience visiting and painting rock art sites across North America and Australia, with an emphasis on Wisconsin and the greater Lake Superior region.

Robert "Ernie” Boszhardt is a professional archaeologist with more than forty years of experience, the vast majority in Wisconsin. He worked for the Mississippi Valley Archaeology Center at the University of Wisconsin–La Crosse for nearly thirty years and is now an independent archaeologist and an honorary fellow at the University of Wisconsin–Madison.
