The Blood of the Ancestors Grotto (11SA557), first documented in 2005, affords iconography both familiar and uncommon. Of the 46 discrete, prehistoric expressions, we find many images thought associated with spiritual power and healing. While our knowledge of iconographic expressions of femaleness in Midwestern North American rock art is quite limited, we also here find images possible to interpret as associated with females. When taken as a whole and viewed in the grotto's unusual biophysical context, the site's potential function as a place of female learning and healing is most intriguing. Our observations and thoughts are offered in a spirit of interpretative exploration.
