Good question, Exxon, there is not an official answer, it's merely for presentation, but for me, I find it is more organized, less cramped, "Double Spaced" rather then "Single Spaced" the idea came from a very common layout "North, East, West & South" or "Spring, Summer, Autumn & Winter" I thought I could make it more interesting the way I did it. For easy navigation and presentation.
Remembering where is where is not as hard as it seems,
Ex: The Hot; Volcano, Hot springs, Creek, Hill
Volcano's are hot, duh, Hot springs are too, the creek has its explanation on how and why it is hot, and the hill is always in the sun because there is no trees.
All the other water like places are in The Cold; Water Falls, River, The Lake.
You may wonder why the farm is there it is because it was originally going to be a "Prairie" which are always windy so cold... But it was changed last minute.
Hope I helped?
