INAH Finds Petroglyphs Spanning 3000 years in Colima, Mexico
INAH has found 100 petroglyphs, with assorted iconographies and cultural affiliations, covering a period of over 3000 years (1700 BCE-1520 CE) at the site of La Campana in Colima. This is one of the few sites in Mesoamerica that has evidence of all the stages of Mesoamerican history. These petroglyphs are within the new La Campana archaeological park. This will protect the entire pre-Hispanic city for future research. The glyphs represent zoomorphs, stripes, numerals flowers, hearts, faces.
There is a stone with faces from 400 BCE, a Teotihuacan style glyph from 400-600 CE for example. INAH also excavated a retaining wall with steps next to the Colima River. The area is served by two rivers and was a good space for cultivation and trade.
INAH has the report (in Spanish) here with a good slide show (click on the small green camera icon);
