 The appearance of the site varies among cultures, but it is often associated with stone arrangements, rock engravings, or other art works.In the bora rites of southeastern Australia, two circles were drawn, connected by a pathway, a schema which appears to replicate a sky Bora, or the configuration of a series of positions in the Milky Way.Typically, bora ground comprised a larger circle with a diameter of between 20–30 metres, and a smaller ring around 10–15 metres in diameter.
