Well, I finally figured out the initial configuration of my second level mining area.
Everything that shows 'cardboard' will eventually covered with scenery. There
may even be more mining facilities. The few elements that I've fit in now still
need more work and finishing.

This upper tunnel portal will (hopefully) be 'blended' into the mine facility, as if it's attached to the mountain.

This just another viewpoint of the same area from the opposite side.

An overall shot from the end of the second level. Everything in the mining area is still removable. I remove
everything, then work a little bit on the scenery, then replace a building, see how it fits, then remove it again
and make adjustments, reinstall, etc...

This last shot gives an idea of how big the 'mountain' will eventually be. That long horizontal piece of
cardboard in the middle of the pics is the lower end of the tunnel. I have no idea what's going to be in
that area yet.
