The method I use to show contour lines is one I learned in the Boy Scouts and it is how I finally grasped the concept.
As I mentioned in the first video I think a good understanding of contour lines and a good topographical map will allow you to find your location in the woods and navigate without any other tools.
I am not suggesting you do not need a compass for land navigation. However, the ability to visualize map topography will allow you to recognize terrain features in a way that a compass bearing can not do.
Once I learned this skill I never got lost in the woods again. But if I was honest, I would have to admit I didn’t really get lost in the woods much before I had this skill. I grew up in a State Park and knew those woods like most kids know their neighborhood.
I used to turn my radio up loud, lock my door and sneak out to go walking in the woods.
