LUCY CORRANDER - PICTURES JUST PICTURES - MOSSY ROOTS - JANUARY 30TH 2010 - SONY DSC-T77 - DSC05939tempsatcontunfadcr
Following Hermes' comment . . . the view below is of the East Facing side of the tree.
The tree is at the foot of a tall, steep bank in woodland so there can never be any sun from behind it (the West) and very little, and only for part of the day, from the East. I couldn't stand far enough back to give a full idea of how wide the roots spread (there were more trees and a river behind me) but by showing the whole frame from which I cropped the main picture it can be seen that Hermes is right in that there is noticeably less moss on the Eastern side - from which is likely to come the only direct sunlight in the day. In terms of sunlight - almost every other side of this tree faces North!
