His talk will be on his forthcoming book entitled Ancient Astronomy of Central Arizona. He will describe his five-year study of prehistoric sites in the Verde Valley that led to the discovery of several astronomical observation sites created between AD 1000 and 1350 by the ancestral pueblo cultures at that time. He will also discuss and show images from his recently completed two-year study of the astronomical features of the Casa Malpais Ruins in Springerville Arizona. In addition to his conclusions at the circular observatory structure, Ken will show several structural and rock art calendar markers that had previously been undiscovered.
