C.] (12) and Waywaka in the central Andean highlands in Andahuaylas (≈1500 to 1000 cal yr B. The gold may thus date significantly later in time, and recently the dating of the ceramic assemblage has been revised downward and may be no earlier than 1000 cal yr B. Both sites were inhabited by settled village agriculturalists capable of generating surplus, and in the case of Mina Perdida the inhabitants constructed impressive corporate civic-ceremonial architecture. Geomorphological data from the Ilave river drainage (18) and limnological data from Lake Titicaca (19, 20) show that a key river terrace—Terrace 2—was created by ≈2300 cal yr B. as the level of the lake rose from a much lower level in the mid-Holocene. Geophysical survey and extensive excavation revealed the presence of five pithouses arranged in a circular pattern.Until the discovery of gold at Jiskairumoko, none had been found in the sites of transhumant low-level food-producing peoples. Over the next 2,000 years increased precipitation led to terrace aggradation, creating a favorable environment for an increase in the density and abundance of plant species of dietary importance in the region, most notably spp. Settlement data from the Ilave basin reflect population growth, settlement aggregation, and the movement of large sites toward the Terrace 2 margins during the Terminal Archaic (17, 18). Storage alcoves within each of these structures had total capacities ranging from 130 to 150 liters.

The earliest published sites with gold artifacts or evidence of gold-working technology are Mina Perdida in the Lurín Valley [1410 to 1090 calendar years (cal yr) B. Although the stratigraphic context of the gold at Waywaka appears to be secure, it has been dated only by association with a ceramic assemblage that has a wide chronological range. We have chosen to be conservative in our assessment of the age of the gold. Multiple lines of evidence attest to this transition.In these societies, gold was generally used to signal high status and was frequently incorporated into the dress and costumes of elite individuals.Based on this association, the tradition of gold working has often been associated exclusively with a high degree of social and political complexity, wherein elites supported craft specialists and provided them with access to necessary raw materials (1).A decision was made at the time to remove the pit contents as an entirety and to examine the burial in a secure laboratory context to preserve as much of the bone as possible and to avoid the theft of the gold because looting at the site had been a problem.The pit itself and the resting spot of the burial are well defined and, as noted above, do not show evidence of disturbance (Fig. Nine gold beads were discovered near the base of the adult cranium close to the mandible.These include displays of valued objects that have been seen as the material manifestation of aggrandizing behaviors as individuals, families, or other social factions compete for status and new leadership positions (3–5) or may also signal differences in lineage, age, gender, or ethnicity.

Objects composed of exotic, nonlocal, or difficult-to-obtain and difficult-to-process materials are frequently used in status display and competition.

The juvenile was between 4 and 6 years of age based on fusion of the cervical neural arches.

The adult cranium rested on its right side and faced the bottom of the burial pit.

The Terminal Archaic pithouse is indicated with the uppermost arrow. The surface of Level IIIc (indicated by the dotted line) is clearly defined by stones and pit outlines.

Excavations at Jiskairumoko, located in the Río Ilave drainage of southern Peru, have revealed a transition to sedentary life beginning in the Late Archaic around 3400 cal yr B. The primary components of the diet consisted of ) and camelids] (17, 21, **).
