Choosing a route in the forest

In the picture

1. 1Contour map: hills, streams and open or wooded areas shown in detail
2. 2Thumb compass: the red needle points north so you can turn the map to match the land
3. 3Control flag: the next point to reach, marked on the map
4. 4Winding path: a longer but easier and faster-running route
5. 5Straight line through the forest: a shorter route that crosses slopes and thick undergrowth

Examples

• Choosing a longer trail around a marsh instead of wading straight through it
• Turning the map until north lines up with the compass needle before setting off

Quiz: Choosing a route in the forest (Age 16)

1. 1

   On the map, the control flag is straight ahead. Why might the shortest line still not be the fastest route?

   • Because hills and thick undergrowth can slow you down more than a longer, easier path would
   • Because a compass works less well when you walk in a straight line
   • Because a map never shows distances accurately
2. 2

   What do you use the compass for when you read the map?

   • To measure the distance to the control flag
   • To turn the map so it lines up with north and matches the land
   • To show which route is the fastest
3. 3

   In unfamiliar terrain, how should you choose between a winding path and a straight line through the forest?

   • Always take the path, because paths are safer
   • Always take the straight line, because it is the shortest
   • Weigh the extra distance of the path against the hills, trees and wet ground on the straight line
