My neighbor recently visited Northern Canada on a hunting trip. He took a great many photos. Upon review, I noticed they have very tall and skinny pine trees with very full tops. He described the soil as very thin, perhaps less than 12", and solid rock below. Accordingly, I'm wondering if anyone is knowledgeable about the characteristics of these trees. It appears they are skinny to resist wind resistance. However, given their height and the reported soil thickness, I would assume the root systems would resemble an inter-woven quilt through the soil and above the rock? Any clarification would be greatly appreciated.
