There are also both line and point symbols for stairs.  The line symbol won't work.  I need to check the point symbol to see how it works.  The stairs in Stark Caverns go around several curves.  I might wind up using visible borders, or perhaps repurposing the rock edge symbol, and then just drawing the steps individually.
