I Suppose every digger has at one time or another yearned for a potoscope or dreamed of an archaeologicallyrendowed hazel bush whose twigs would tug and dip to well-stocked graves. But if such sure-fire indicators existed, I doubt if fieldwork would be as much fun as it is. Would fishing have quite the same lure if every cast brought a strike? For better or worse, archaeology is a great gamble; each new site offers unlimited possibilities of surprise. So although the introductions to our reports often let it be inferred that our finds have been the result of keen scientific foresight, very few excavations, I imagine, turn out as we expect them to. It was certainly that way at Kaminaljuyu.
