This tabletop activity features the eastern horizon as seen from one of the most astronomically remarkable structures in Chaco Canyon -- a Great
Kiva that some call Casa Rinconada. There are many different names for the place given by the 21 Native American tribes who have historical and
ancestral connections to Chaco. This activity invites participants to consider how the sunrise position on the eastern horizon changes throughout
the year and how this can be used to create a so-called “horizon calendar.” Their inquiry is guided by a live facilitator.
