The landmark in my photograph is Fajada Butte, a prominent geological formation located at the south entrance of Chaco Culture National Historical Park in northwestern New Mexico.
Rising roughly 400 feet above the canyon floor, it is most famous for its archaeoastronomical significance.

Anatolian finds at Gobekli Tepe, Karahan Tepe and Catalhoyuk show advanced sky-watching, social complexity and hazard planning - reframing prehistoric astronomy and linking these discoveries to modern UAP research. 2026 field tour announced. #Archaeo #UAP
Ancient Anatolian Discoveries Revive Debate on Prehistoric Astronomy, Catastrophe Memory, and UAP Context
Former F-16 pilot and UAP researcher Chris Lehto reviews recent findings from Göbekli Tepe, Karahan Tepe, Cappadocia, and Çatalhöyük, arguing they indicate sophisticated sky-watching, social complexity, and long-term hazard planning in prehistoric Anatolia. He links these developments to contemporary questions in UAP research and announces a 2026 field investigation tour to document archaeoastronomical features and fresh excavations.

Psicoactivo examines Peter Levenda’s first‑contact thesis on ancient civilizational leaps
The Psicoactivo Podcast highlights author Peter Levenda’s claims, as discussed with Jesse Michels, that an initial contact with a non-human intelligence may have catalyzed the rise of agriculture, writing, and astronomy. The segment connects archaeoastronomical alignments, cross-cultural myths, and Tom DeLonge’s related assertions while acknowledging scientific controversy over human evolution and genetic evidence.

I think very few archaeoastronomical claims of architectural alignments are really firmly established.
In Mesoamerica archeologistst tend to be extremely skeptical even of solstitial alignments actually mentioned in written sources, like the Templo Mayor.
