Well, it has been a while and here's only a small part of what I've worked on today...
This is to compare today's version of the lava chamber of the FireBreath Volcano with (as far as I'm concerned) the original from 2005-06 but may have had an event fix and rocks thrown in in 2007. The only reason why the walls of the current version are 5 tiles tall instead of the usual 3 is because you drain the lava in the beginning of the dungeon and then jump down a 2 tile high ledge. The differing levels of lava throughout the dungeon are supposed to be that way, as underneath the lava they are all on differing layers of rock that pour into the middle. When you go through the lower sections they'll appear 2 tiles below the walk way, as I really don't care to add another lava drain to empty out the upper layer. 13/17 sections of the volcano are currently completed.
EDIT: Mapping has been completed for the FireBreath Volcano, now all that must be done is event work.
