How To Find North

It's also useful to know that the top of a map is always pointing North, so all you have to do is match that with North on the ground.

This is easy to do if you are carrying a compass, which Crackers would normally do if he had organised a walk for them. And they've learned how to use a compass before - read all about that here.

But what would happen if they didn't have a compass with them? How would they know which way was North? First of all if they were in a strange, new town? Crackers had the answer to that: In towns, you can usually work out which way is North by looking for satellite dishes attached to houses. In this country (and all of the Northern hemisphere in fact) they will be pointing South, so then North would be in the opposite direction.
