It was in the excavation of the circular stone feature. The probe was a half-inch rod about 8 ft. long that Alex tried pushing in on the perimiter area a couple of times. With no T-handle, it looked a little awkward, then he got down into the hole and slammed it into the ground once or twice. Not good had there been any fragile artifacts in his way!I was watching parts of it, I must of missed the probing part? LEON.
