I am not sure you mean the highland cloud or soul. If you are talking about cloud,it is easy to see. If soul, I can understand,please point out. About ground heat I would like to introduce New Zealand. At Routorua [southern part of north island of New Zealand] ground heat is famous,people living there use ground heat as energy to cook,to boil water and even store dead body in coffin over a ground heat construction.
