Several large fire-burnt stones came from Level 120-140 cm. Sterile 

 black clay at a depth of 160 cm. established the bottom of the midden 

 accumulation. 



The site of 0-5: Embarcadero is about 5 km. inland from the mouth 

 of the Estero Embarcadero (fig. 4), where the left bank rises to 2 m. 

 above high tide level. Shell refuse was visible for a distance of about 

 150 m. along this bank (pi. 4, a). The midden area slopes off to the 

 surrounding land, which measures roughly 1 m. above high tide, a 

 contour that is easily seen from the water. Along the eroded bank, 

 vertical columns of shell about 10 cm. in diameter and about a meter 

 long could be seen in several places, possibly representing former post 

 holes. The site is densely overgrown but the midden deposit could 

 be traced for 30-40 m. inward from the bank. Miscellaneous testing 

 showed that sherds were fairly abundant throughout. A 1 X 1 m. 

 stratigraphic excavation, designated as Cut 1 and controlled in 20-cm. 

 levels, was placed 50 cm. in from the edge of the bank. The refuse 

 consisted of hard, lumpy clay with an abundant admixture of shell, 

 sherds, some fishbones, and small broken rocks. Sherds were present 

 to a depth of 80 cm., where a dense layer of shells 20-25 cm. thick 

 was encountered. Below this was sticky clay, the natural soil of 

 the bank. The only unusual artifacts were a pottery figurine arm 

 from Level 20-40., cm. and anther figurine fragment from Level 40-60 cm. 



None of the sites investigated in the Playas-Posorja region pro- 

 duced any human skeletal remains. White-on-red pottery was 

 collected by Estrada from Site P-4, which consisted of a small circle 

 of erect stones with two extended burials in the center (Estrada, 1957 

 a, p. 28 and fig. 10). Site 0-7: Tendales, reported by local residents 

 and not visited by any of the authors, produced human skeletal 

 remains in association with ceramics of Jambeli types. This site, 

 discovered during excavation of irrigation trenches, is reported to be 

 several hundred square meters in area. 



For ease in reference throughout the report, sites belonging to the 

 Jambeli culture are listed below. Group ''A" includes those from 

 which sherd collections have been classified and which appear in 

 Appendix Table 1. Group "B" includes sites in the ^alitres where 

 no sherds were recovered, but in which the character of the site, its 

 location, and the composition of the shell refuse are typical of the 

 Jambeli Phase.
