Pyramids in Colima, Mexico

You may remember my earlier post about the pyramids of Teotihuacan, Mexico... Well, Colima had pyramids, too. The pyramids are probably 1/10th of the size of the ones outside of Mexico city. These pyramids are located in Villa de Alvarez, which is, also, the town where the college that I attended was located. Here is some more information:
El Chanal - archeological zone located some 4.5 kms. north of Colima. First explored by archeologist Vladimiro Rosado Ojeda in 1945, the site extends over some 140 hectares on both sides of the Rio Verde. It comprises ceremonial plazas, altars, pyramids and several ball courts. Particularly prevalent on the site are figures of the Rain God, Tlaloc. Characteristics of artifacts made of clay and obsidian with the use of metals indicate that the inhabitants of El Chanal were in some way related to Tula.The biggest and the oldest archeological zone in the state is "La Campana" from 600-900 AD. La Campana is located in Villa de Álvarez between ITC (Tec de Colima) and "La Comercial" mall. La Campana has the only "Tumba de Tiro" open to the public in Colima. Inside the grave you can see handmade figures like the little dogs and old instruments made of mud and obsidian. ( http://sparks-colima.blogspot.com/2006/11/ruins-of-el-chanal-and-la-campana.html )
