  We test the hypothesis that Aboriginal linear stone arrangements in New South
Wales (NSW) are oriented to cardinal directions. We accomplish this by
measuring the azimuths of stone arrangements described in site cards from the
NSW Aboriginal Heritage Information Management System. We then survey a subset
of these sites to test the accuracy of information recorded on the site cards.
We find a preference recorded in the site cards for cardinal orientations among
azimuths. The field surveys show that the site cards are reasonably accurate,
but the surveyors probably did not correct for magnetic declinations. Using
Monte Carlo statistics, we show that these preferred orientations did not occur
by chance and that Aboriginal people deliberately aligned these arrangements to
the approximate cardinal directions. We briefly explore possible reasons for
these preferred orientations and highlight the need for future work.
