my guess on a measurement would be a soldiers vara, = 33+- inches,, but the more i look at picture i would think the circle stood for mine,treasure,, or mountain, knoll......in the direction the turtle is heading..........the triangle with dot in center is on the large rock on the left of first posted picture.......if the triangle was upside down the cache would most likely be marked by a triangle of trees, but the way it is means marked by triangle of rocks,, most likely three rocks, one at each corner, also either sitting mostly by themselves or marked so you would be able to discern the right ones..cache most likely centered as shown by raised dot in center..........head in the direction the turtle is going {unless tail or leg points oddly} looking for three rocks or possible rock markers making triangle, and check center.......i also think that if they were moving these big boulders around that the cache would be buried according to regulation = the depth of a soldier = 5-6 feet deep..at least...........gldhntr
