I was going through some old photos, trying to find a "spring like" photo for my laptop's wallpaper. Anyway, I run across these photos. There were many large trees in the very spot we built the retreat. The old cabin is the 'gathering room' with the fireplace. The back door of the cabin is now removed and that is where you transition from old to the new addition.
The steps to the bedrooms in the basement come down off the back there.
