 But here comes the confusing part; when you ask Therion to include these scraps in your drawing, most of these features do not show up, because they are not inside a "cave" passage.
-In XTherion, right click on the lines you have drawn. Select "other options" - "clip" - "off", or manually set the "-clip off" option in the Lines panel. The lines will now be allowed to appear outside of any cave passages. For best results, keep your surface features within surface scraps and maps, so that they can be excluded or included from the resulting PDF output as desired.

-Certain surface features do not have any nice way to represent them, however, such as a tree that is used as a natural belay for a pitch. Consider creating your own tree symbols using Metapost (and share it with the rest of us, please). Or if it is large enough, draw it manually using borders, and try making it look nice. Good luck, and happy sketching.

 Note that it is not easily possible to ask Therion to shade the ground in one colour and the sky in another (when drawing elevations through a mountain, for example). To do that, you would have to draw the surface as a "cave" wall, and draw an opposing "wall" below the altitude of the actual walls of the cave, and use "break" to place it behind all of the actual caves. Then style that scrap with the colour of your choice. It is messy though - if you have any other solutions to this problem, please share them here.
