"You won’t find any prehistoric pueblos or cliff dwellings in Waterfall Canyon, but this cactus-covered patch of desert in the White Tank Mountains contains enough ancient rock art to make it a worthwhile destination. The trail leading into Waterfall Canyon passes through the site of a village that, according to a 1963 report by archaeologist Alfred E. Johnson, covered 75 acres when it was occupied by the Hohokam between A.D. 500 and 900. No walls or other major features of the village have survived to this day, but all along the trail you can see boulders covered with petroglyphs.
One of the more impressive petroglyph panels, located on a large rock on the north side of the trail only ten minutes into the hike, includes a sun, a stick figure, something resembling a garden rake, an image formed by two perpendicular zigzag lines and other drawings. The sun and stick figure seem straightforward, but one can only guess what the other pictures represent. The rake design appears at many petroglyph sites, and some archaeologists believe it may represent a net or fence used to divert and capture game. The zigzag lines, located immediately left of the rake, may represent snakes or, perhaps, squash vines."
