From the start of the paper:
Images of flowers hold special meaning to speakers of Uto-Aztecan languages throughout the Southwest and Mesoamerica. Flowers represent a flowery, colorful, glittering paradise that can be evoked through prayers, songs, and other human actions. Flower imagery representing this spiritual landscape, the Flower World, have been reported in kiva murals and ceramics; in 1992 Jane H. Hill’s work suggested that such imagery might also be found in rock art. We report here that flower images are among the prehistoric petroglyphs at Sutherland Wash Rock Art District near Tucson, Arizona. Some petroglyphs are realistic representations of flowers, and others are more abstract forms associated by other researchers with flowers and the Flower World. Additional features associated with the Flower World are also present, such as images of birds and butterflies as well as sparkling, crystalline rocks in the landscape.
