“Visions in Stone: The Rock Art of Minnesota”

To date, only about 55 or so prehistoric American Indian rock art sites have been recorded in Minnesota and many of these, since destroyed, were first identified in the late 1800s. Recorded rock art sites in Minnesota include petroglyphs and pictographs appearing on exposed rock outcrops or in caves, as well as open-air petroforms. Minnesota’s aboriginal rock art appears to have been produced from Archaic through protohistoric times and was probably produced in Paleoindian times as well. This program will include a discussion of the state’s rock art — how we have recorded it, how we have interpreted it, and how we have misused and abused it.
