Bora ground orientations
Sixty-eight bora sites in NSW and southeast Queensland prefer the southern quadrant, matching the Milky Way’s late-winter stance.
Fuller, Hamacher and Norris (2013) measured orientations and ran a Monte Carlo test. A clump of 35 in the southern bin is vanishingly unlikely by chance. They argue the builders aimed most rings toward the south-southwest, where the Milky Way stands vertical after sunset in August.
Anderson’s published emu story links that season to eggs hatching and to Elders nurturing initiates, as male emus raise chicks. The paper is careful. This page is too. We cite the statistic. We do not simulate a bora.
In /sky the August setting can show the published egg-and-rings appearance of Gawarrgay. The site object exists so the archaeology has a catalog card, not a 3D ceremonial ground.
