60' tall, 20' wide passage filled with breakdown and clay. The route of travel alternates from over, under, or through the breakdown. Sometimes two or more routes are possible. I have about 2000' of this "problem" passage, how do I sketch it? A plan view showing the theoretical location of the actual passage walls would more accurately describe the nature of the cave, but wouldn't help much with route finding. A plan view showing the actual route of travel through the visible passage would be a sinous up and down affair, while the cave is actually big, level, straight. I've worked out what I think is a compromise, which I've shown a segment of below, but I'm still unsure of it. Tell me if you think it makes sense. Also, do you have any suggestions for x-sections in this kind of passage? Should I try to show the traversable passage shape only or include its assumed relation to the rest of the filled passage? Or...should I try to include a profile?
I know these are very common issues, and I thank you for your patience in explaining solutions to a novice.
