Anasazi Sun Dagger
Why it was built
Geographical info
Function
How it works
Links
During the Summer solstice, a dagger of light can be seen bisecting the spiral for around 20 minutes. During equinoxes, a dagger of light can be seen cutting the midpoint (4.5 in 9 spirals) between the center and right side of the spiral. A light dagger can also be seen cutting through a smaller spiral during these events. During the Winter solstice, two daggers of light appear on both sides of the spiral framing it for around 50 minutes.

The observatory was built in order to track Solstices and Equinoxes as they marked the change in season, helpful for managing crops.
The position of the sun dagger seen in the observatory helped the Anasazi keep track of seasons for agricultural and ceremonial purposes. A theory suggests that the sun dagger was also used to view the movement of the moon over time.
The observatory was built in order to track Solstices and Equinoxes as they marked the change in season, helpful for managing crops. A theory states that the possible original plan for the observatory was to be a shrine for the sun.
