Mike Ruggeri presents a special summer report on 

Enigma of the T-Shaped Doors in the Ancient Southwest

Mysterious T-Shaped doors appear in the Ancient Southwest and in Mesoamerica for almost 700 years, starting at Chaco in 850 CE. Very little study has been done on this enigmatic phenomena. What is the meaning behind these T-Shaped Doors? Where do they appear in the Ancient Southwest and Mesoamerica? How do they change in their dynamics over time.

Mike Ruggeri will take you on a wide ranging illustrated lecture of these mysterious doors from New Mexico, Arizona, Utah, Colorado, Chihuahua, and the Sierra Madre as he begins to explain what is behind this enigma.
