UPDATE
The Measurements you'd have found when the
markers were still there were:
North: 15
West: 22

The co-ordinates will take you to a stone bridge where, if you do not already have the numbers from Hand Pi #1, you will need to take two measurements in metres. Round both to the nearest m.
On the North side of the bridge, measure between the post with the green reflector and the North edge of the stone bridge. On the south side of the bridge, measure between the yellow and black striped sign and the post with the red reflector.
