Alta Vista has been investigated by archaeologits Manuel Gamio , J. Charles Kelley, and Archeoastronomer Anthony F. Aveni. The researcers found that the complex contains solar significance and a deliberate placement on the Tropic of Cancer by builders of the Teotihuacan culture.
A solar equinox alignment and a summer solstice alignment of the sun over a distant mountain at dawn and two Teotihuacan style, circle-cross petroglyphs carved into the cliffs at that mountains led to the conclusions that Alta Vista was a Teotihuacan ceremonial outpost at the northern limit of Mesoamerica.
Alta Vista's Solar Equinox Alignment
The equinox and a summer solstice alignment of the sun over distant mountains Picaho and Chapin at dawn and two Teotihuacan style petroglyphs carved into the cliffs led to the conclusions that Alta Vista was a Teotihuacan ceremonial outpost.
J. Charles Kelley authored a book about his investigations at Alta Vista
Alta Vista has been of interest to Archeoastronomers because of solstice alignments and its deliberate placement on the Tropic of Cancer by builders of the Teotihuacan culture.
June 21 marks the solstice, that is zenith day at Alta Vista
Alta Vista or Chalchihuites, as the ruin is called, was built deliberately on the Tropic of Cancer by builders of the Teotihuacan culture according to researchers. The site is a solar calendar for the tracking of the movement of the sun over the earth.
Alta Vista is at the northern limit of Mesoamerica and has led archaeologists to believe that the site was a ceremonial outpost built by the Teotihuacan Culture due primarily to circle-cross glyphs etched in distant cliffs.
The site has panoramic views of distant mountain peaks where alignments have been noted during the equinox and solstice.
The site has a museum. The nearby town of Chalchihuites provide lodging and limited services for visitors.
Many visitors come during the Zenith days of June 21-22 to note the alignments created by the builders.
Alta vista archaeological site includes a room of colums which appears to have ritual significance.
Because the columns are so closely placed they appear to have significance other than structural, and could have served as markers of the zenith, as a column will show no shadow at its base on the zenith day.
