Where it stands

Three answers have been proposed. Most great houses face south to south-south-east, continuing the orientation of earlier pit houses and unit… leads, with evidence 2 for: partly supported by its tests. Two are still possible.

Why it matters

The Solstice Project's survey is the main evidence that Chacoan builders built the moon as well as the sun into their largest buildings. The alternative is that the orientations follow an older house plan and the lie of the canyon, and that a few cardinal walls and solstice sightlines are the only astronomy intended⁠[1]⁠[2].

Not tested enough to call either way
