yes it can be dowse,but google earth is few month old,and they are moving dirt every day, so i feel its a wast of time,now on the other hand,if you learn to dowse,you could take a camera take pictures,and printer,and dowse them at night and know where to look the next day,right now it seems to be more hits in southwest corner,but they could be gone now,are moved on up the field.i'm not for sure, but i think they work the dirt about every week.
