Interestingly I did my dissertation on this site.
Several particular points came up when I was evaluating its defensibility, such as much of the thought around it being indefensible comes solely from the results of the excavations of 1893 and 1894 (over a hundred years ago, and also preceding several years of constant change in archaeological theory and methodology, as well as interpretation) and modern viewpoints about its positioning.
In addition, there were several discrepancies between Shillabeer's map of 1829 and the DEC map of 1893/4, including several missing features and structures that could tell a different story!
Something is not right. This message is just to keep things from messing up down the road
