As I originally posted, a location on Geronimo Head seems to fit the description as recorded in "Dr. Thorne's Gold" by Barry Storm and in Bark's Notes. By standing at a certain vantage point, a person could look far below into LaBarge Canyon. At the top of the mountain and to the right of a ravine, looking ahead, a disturbed patch of ground could be seen with a "dump" of rocks nearby. To the left of the ravine, a spur could be seen with rock "ruins." Looking down into the ravine from the "ruins", rocks arranged in a linear pattern could be seen, as if forming bulwarks to protect an adit dug into the slope. Study the second GE image and more linear arrangements of rocks can be seen on the top of the spur.
