The picture below lets you look through and old Arbutus (Madrona) stump. The point of land in the view is nearly perfect "Due South" and the log in the foreground is hollow so I took a similar photo through it.
We finally got back to the cabin and walked around a bit on the small island. I'm exhausted - have not walked that much for a years or two.
I'll post some more pictures, not tonight, though.
Later: I'll try to describe the existing hole these pictures were taken through:
When we purchased the lot on the island in about 1990 there was a massive Arbutus tree leaning almost to the horizontal which had grown completely around a fir tree and killed the top of the other tree. The top of the 10" fir was all gone but the stump was fastened into the trunk of the leaning arbutus and supporting the larger tree allowing the arbutus to reach even farther out to the cliff for the sunshine it was seeking and grow to large dimension for such trees. I wondered if the arbutus was not sustaining the stump of the fir because it was obvious the big tree would not stand without support. Eventually the whole arrangement started to lean toward the cabin we built there and a couple of the guys went over with a chainsaw to take some of the weight off the upper (farther) part of the arbutus. When I saw what they had done I said: "They took the wrong side off." The support system went on leaning into the sundeck and one wet spring the roots began to pull themselves out of the thin soil and the tree lean so drastically we decided to drop it before it reclined on the cabin or the deck. We hired a climber to bring it down in pieces and still lost most of the top over the cliff. Th edge of the cliff is at least 30' from the stump. I get there and see the section of the arbutus with the hole where the fir went in waiting to be bucked up for fire wood and a large handy stump near it. Just for fun I wrestled the hole thing upright on the stump, oriented the hole to look due south (true) and spiked it all together.
I figured we can always cut the arbutus up for fire wood but even "All the King's Horses" could not put that hole back together again. I'll post a picture.

maybe I should set up a web cam in this stump
