This hand-constructed coiled basketry bowl is characteristic of the Tohono O'odham (formerly Papago) or Pima cultures of the North American Southwest. The vessel is crafted using a coiled technique with natural plant fibers, including yucca or willow for the buff-colored ground and martynia (devils claw) for the dark brown decorative elements. The walls feature a repeating three-tier stepped geometric motif. The rim is finished with a ticked pattern of alternating dark and light vertical stitches. The base displays a tight spiral start accented by a single dark concentric band. The weave is tight and consistent throughout. No maker marks, labels, or signatures are present on the surfaces.
