Dr. House: After a few messages back and forth about this one with carnigrewal, I decided to take a walk out to it to check up on it on my way home from a day of caching in Brantford. I'm happy to say that the cache was right where I had placed it originally, which was, in fact, the tree in the picture that had been sent to me via email. It was covered a bit by snow and leaves and whatever else, but was still nice and dry. Had a nice lanyard on the inside, too.
I, too, found the co-ords to be off, which is unsurprising given that all the Advents seemed to have shift issues from my Garmin Colorado. It's off more than my liking and given the nature of this puzzle, I've decided to archive it as a result, rather than re-work it.
