These are depictions of Hohokam people carrying burden baskets, a common theme on Hohokam pottery. In later Oodham culture burden baskets are made of saguaro stick frames with agave fiber cord lace coiling. A strap carried the weight on the forehead, while a pad protected the back. This vessel dates to circa A.D. 850-1000 and comes from Four Mile Site, Painted Rock Reservoir, Maricopa County, Arizona. It is on display in the Arizona State Museums Wall of Pots. The museums collection of Southwest Indian pottery includes more than 20,000 whole vessels, which are housed in a large, climate-controlled vault. The oldest pot in the collection is a seed jar, or tecomate, which dates back to A.D. 50-150. It was found at the Stone Pipe Site, near the Interstate 10 frontage and Prince roads in Tucson.
