Wilderness till you survive (1)

"Right once again I am Major Wilson. I will be your professor for the Map and Location for wilderness 101". As the Major speaks some of the cadets would begin opening their book, then the Major would interrupt "I prefer don't open your books yet cadets, because what we will do is mostly practical work and not knowledge exams so better write down the things I will discuss.".

After those words, the Major would begin to discuss. He started opening his briefcase and pulled out a thick paper that was inside the folder with a fastener and then it was followed by a few introductions about the terrain and the calculations that were needed to differentiate the map. While the Major was discussing he would then turn around and simultaneously begin sketching the map on the board.
