The petroglyphs in Montana are special because they really focus on the story of ancestors in the area. I learned a lot about the family who lived on the site who had lived there for many years. Billings Gazette covered the pieces in 2019 and included some fantastic pictures. The carvings here being the early settlers, the pickup trucks, and father and son tractors.
There are a couple others at this site as well, as shown in the article. Good read. A PDF version is available on the press page here at petroglyphist.
