This control is a little more testing for two reasons.

Firstly, despite its size, this boulder is still smaller than the equivalent area in the terrain of the symbol used to mark it on the map. With such point features the centre of the circle is always on the centre of the feature, not offset in the description direction in Column G. There is therefore no direction assistance from the map, as with the first control.

The second reason for it being more testing is that the direction of view is to the south, whereas the pictorial description in Column G is to the north, not so difficult with a N-S inversion but more tricky when there are E and W components.

The direction of view from the decision point is S to the centre of the boulder. Flag B is on this direction of view and therefore on the N side of the boulder.

Solution: Flag B.

Advanced tip

If the track permits sighting through a flag to the centre of the boulder, as it does for Flags A and B in this example, a precise check of flag position can be carried out in the terrain. This is much more definite than
estimating a direction off to one side, as in the photograph. Had Flag C been suggested by the description, it would have been necessary to go round to the path west of the control to view it from the W or SW.
