Just down the road from me (in the country) there is a field where a massive old Cypress tree, with a trunk maybe 2 metres (yards) in diameter, had been blown on to its side many many years ago. (maybe as much as fifty?) Just like your drawing. Half of the roots were exposed and some had since died off and become dead wood. The branches on the lower side of the tree - touching the ground supported the tree from falling any further and probably even layered themselves into the ground. The massive canopy had grown upright again just as normal.
I have been driving past that tree for years and every time I did I thought I must take a picture of such a rare sight. Last time I drove past, it had been chopped up and burnt. Probably for no better reason than because it was there.
