Hi Martin,

Good job spotting these settlements and tracks.

It is a good idea to tag the forests as they are part of the instructions.

It is also asked that you map rivers and streams if you can find them.
And I am fairly sure that all these patches of woodland are in fact
covering such rivers and streams.
Have a look from high above:

All the best
