There are a few theories in circulation to explain these piles of stones but none of the explanations put forward yet seem entirely credible. With the area slated to be developed into a wildlife reserve, part of a national park, it is hoped research will be completed on the stones before development proceeds.

There are several concentrations of the piles, some relatively small, some covering a vast area. The piles, often a few dozen stones piled into a small circular pile, number in the hundreds, if not more. Some of the stones are piled into regular shapes like rectangles while, in other cases, the shapes are curved. In one area, there are, for example, rectangles arranged in parallel lines.

In the five photographs above, a Google Earth image of the area where most of the photographs above were taken, some of the patterns are visible, though not obvious. For orientation, some of the photographs above were taken from a low hill; that hill is the dark oval in the center top of the image. The sequence of photographs above were taken from the top of that low hill beginning with a view looking to the bottom right of the picture and ending with a view towards a point at about 10 o'clock on the image.

In the second, third and fourth photographs below, the image was converted to black-and-white, then the negative version, and finally a color-swap in an effort to make some of the patterns more visible.

In the last photograph, some of the patterned areas are circled.
