Okay- this is always difficult, and as an earlier poster mention, the key to really describing the passage will be cross-sections- numerous cross-sections. Of course, the standard is a cross section in the sketches at every station, but everyone knows that doesn't often happen. For the carto side, I think what is important is which layer has more floor/ceiling details that will need to be depicted. It is difficult to tell, in your drawing, for example, if the stalagtites and sodastraws (which should always have a page downward or upward orientation, BTW) are in the upper or lower level. I am going to assume that they are in the upper level. The brown dirt/cobble detail, I am going to guess is in the lower level, but being in a strip like that is very strange with no other floor detail to show the rest of the floor makeup. I think that you could do a couple of things.
The outer wall, regardless of underlaying passage, should always be solid (unless it is unsurveyed, but you indicated that you surveyed the lower level, so there should be a solid wall. The solid wall absolutely takes precedence over an unsurveyed one.) Your left wall changes from solid to dashed, I assume to show that there is an underlaying passage. But there is no indication as to why it changed, no beginning of the lower or upper passage, so why it changed is unclear. Same with the short section of right wall. The center wall being dashed is alright, but again, there is no indication as to why it suddenly started.
The dirt. I cant tell you how confusing the dirt floor detail is. It makes no sense to me at all. If you are going to show floor detail, you need to show consistent detail across the passage width.
Once you have decided which layer to show details for (upper or lower) show all the details, and then notate that upper layer floor details have been omitted for clarity, and show only the walls.
Hope this is a start.
