Plan view showing the distribution of burials and “caches” (offerings) found in a tightly clustered cemetery at the Loma Sandia site. Over 200 individuals were interred in this large cemetery which dates between 850 and 550 B.C. (about 2550-2850 years ago). It is located on a small tributary of the lower Atascosa River just above where that river joins with the Frio and Nueces rivers. Click to see larger image with legend. UTSA-CAR archives.
