Abstract
Three petroglyph shields incised on Alcatraz Rock in southeastern Montana show the same heraldic design. Ethnohistoric information about the general site area, coupled with ethnographic knowledge concerning the acquisition of heraldic shield designs suggests that a supplicant originally obtained the first shield in a vision at this place and later made additional copies of the shield, commemorating them with additional petroglyphs. The shield heraldry appears to illustrate paired Great Blue herons in a fighting pose.
