Documentation of Some Lunar and Solar Events at Casa Grande, AZ. (and other items)

This document includes 4 versions of a report about lunar and solar events at the Great House at Casa Grande Ruins National Monument. These include: a presentation paper, a published version, a version prepared for Arizona Highway Magazine and a Science News summary. There is also a constellation chart to check Canopus alignment. The report outlines basic history and construction of the Great House that facilitates astronomical events. The report references computer data, cutting edge at the time, but sadly outdated today.
