It seems to me that the joint between the segments can be eliminated by connecting all four sections together, covering the gaps with plaster cloth, and creating a single structure that can be lifted off the layout for track access. The bottom edge between the mountain and the layout can be concealed with foliage, rocks and trees more easily and realistically than the joints between the segments, and the hill will still be light enough to remove. I used this technique for a hill and tunnel on my 10'-by-5' layout which will be presented in an article in the February/March issue of OGR magazine.
