Brown wavy lines Contour lines that link together points of land at the same height. This is actually vital information. Hikers may become temporarily misplaced from time to time, but they always know whether they should be going up- or downhill. Experienced bluffers will appreciate that one of the joys of going uphill is that there will come a point when it will be necessary to go back down. On many topographic maps, the difference in height between two brown wavy lines is 5m (16ft). However, in practice, there is only one vital piece of information that you need to remember about contour lines: the closer the lines are to each other, the steeper the climb or descent.
Blue wavy lines Seasoned hikers look for the little blue wavy lines in mountainous areas denoting streams. A method to find out (by merely looking at the map) which way the stream is flowing is to notice that when a contour line crosses a blue wavy line it forms a V and this V always points upstream
Bluffers will also remember from school science lessons that gravity ensures water runs downhill. Therefore, if a blue wavy line gets thicker, you should be able to work out which way is downstream This is even easier if you happen to be standing in a stream at the time. Bluffers should never be seen throwing a ‘Pooh stick’ into the water to determine which way a stream flows.
