Turf bank maze. In order to get as much detail as possible, the survey was carried out at half-meter intervals, resulting in over 3000 readings. Surprisingly, the survey shows the lines and corners of the maze very clearly. The line coming in diagonally from the top right is a track to the water tank. Our biggest problem was the cattle in the field who insisted on lying down right in the middle of the survey area. Infuriatingly, just as we took the last reading, they all got up and moved away!
