Chaco Culture National Historical Park contains ancient ruins of pueblos in New Mexico. There is a lot of speculations as to what Chaco was used for, which makes the mysterious ruins that much more interesting. They were occupied between 900-1150 AD and was thought to be a major trading post for the pueblo peoples. The masonry was made up of only sandstone, timber, and mud. It is truly unimaginable to think of the construction of these places with the lack of resources we have today. Many of the buildings in chaco were designed to align exactly with solar and lunar cycles, and revolve around the summer and winter solstice. When you walk through each site of ruins you can't help but be amazed at the work put into building these places, and also wonder what used to take place in each of these meeting grounds.
