Prior to the arrival of the Europeans, numerous other tribes inhabited Sedona and the surrounding region. Many can still be found here today, including the Yavapai and the Tonto Apaches, as well as the Hopi and Navajo. Some researchers believe that the Hopi and Yavapai are descendants of the Sinagua. 

Evidence of Sedona magnetic anomaly and brainwave EEG synchronization can be demonstrated with portable equipment on site in the field, during sudden magnetic events. Previously, we have demonstrated magnetic anomaly charts recorded in both known and unrecognized Sedona vortex activity locations.
