Summary Description:
A small rock overhang, with a dryish and flat floor measuring about 15 x 6 meters, was located by Anthony J. Ranere and Richard G. Cooke in November 1981, when they explored the watershed of the Santa María River before embarking on the Proyecto Santa María. The overhang is located on the northern bank of the Rio Bermejo, a tributary of the River Mulabá, Distrito de Santa Fé, Veraguas. Its UTM coordinates were not taken. It is probably about 500 m above sea level. A test square (0.5 x 0.5 m) was excavated to bedrock, producing sherds of pottery with a brownish paste, which, suggested an Early Ceramic time period. PSM personnel returned to the rock-shelter in April 1985. They excavated a slit trench measuring 5 x 0.75 m, from the back wall of the shelter to the bottom of the talus slope. This was sub-divided into one meter long blocks. The 0-1 m section was by far the most prolific with regard to cultural material. The profile is complex and difficult to interpret. The upper levels contain abundant post-Columbian potsherds, which probably refer to the use of the shelter by Bugle people after Spanish contact. In lower levels, the pottery is almost uniformly brownish, and painted decoration was not observed. Five radiocarbon dates were obtained. One was run on a carbonized cacao (Theobroma cacao) husk fragment found at 50-60 cm below surface in Block 1. The date is 530 ± 50 BP (cal CE 1310-1365 & 1380 – 1445; Beta-131428). This was reported in: Dickau, Ruth, 2010, Microbotanical and macrobotanical evidence of plant use and the transition to agriculture in Panama, in, Amber M. VanDerwacker and Tanya M. Peres, editors, Integrating Zooarchaeology and Paleoethnobotany. A Consideration of Issues, Methods, and Cases, Springer, New York, pp. 99-134. A date runs on wood charcoal on the same level is meaningless because it has a standard deviation of 250 years (Beta-18862). A charcoal sample found at the base of the block (1090 ± 110 BP; Beta-20847) gave a 2σ span of cal CE 690-1180. Another charcoal sample recovered in Block 1.5-2.0 m at 60-70 cm below surface returned a date of 390 ± 95 BP (1400-1685 cal CE). The shelter is interpreted as a way station for people transiting from the Pacific to the Caribbean watersheds, or a short-term dwelling with few inhabitants mostly during the Late Ceramic and early Historic periods.
