It belongs to the first context analyzed, which indicates the physiographic zone "Montanas"; there is no subcommunity, nor group, site type or structure. The operation is "IV/25" and it belongs to the context "secondary context". This context has a total of 41 obsidian artifacts, 21 artifacts (51.2%) were analyzed. Then obsidian artifacts are presented according to their sources: Ixtepeque, 21 artifacts (100.0% of the obsidian analyzed); La Esperanza, 0 (0%); El Chayal, 0 (0%); San Martin Jilotepeque, 0 (0%); Ucareo, 0 (0%); unidentified sources, 0 (0%).

The quotation marks around "Montanas" and "IV/25" indicate that these variables are alphanumeric and "" indicates the absence of data.

The last (123th) line is:
