Lives of Native Americans

In An Overview of Native American Maps, there are a lot of maps showing the lives of Native Americans. Since Native Americans generally led a primitive lifestyle, the maps they created are basically for finding food, water and reminding indigenous people from the dangers such as wild animals. One thing that interests me the most is how they could manage to create maps with simple materials such as animal skin yet they can be preserved for a long period of time. For instance, in the Lone Dog's Winter Count, we can see that the making of maps is actually very delicate and the symbols were drawn in a detailed way (Warhus, 1997).   As for another reading Maps of the Age of European Exploration, albeit the maps are more sophisticated and drawn in greater detail, the maps tend to be misleading and this makes me wonder the uses of fake maps in ancient contexts. It is believed that some of them may be used for deceiving enemies during wartime.
