Calling Card rock art sites, drawn by war parties in enemy territory to taunt their adversaries by illustrating deeds executed against them, are a newly identified site type on the northern Plains of North America. One such site is Cheval Bonnet, a small petroglyph in Northern Montana. Containing coup counting and horse raiding narratives from the early 1800s, analysis of these images shows that most of the petroglyphs can be identified as Crow drawings, even though they are carved in the heart of Historic Blackfeet tribal territory. Once this site was identified as a calling card petroglyph, I was able to identify three others elsewhere on the northern Plains (PDF available).
