Can't say if that particular one is, but there were a number of thin concrete posts running in a line behind the PB. These had a curved top surface, and appeared to have been supports for a pipeline of some sort.
I also noticed those curve-shaped concrete posts that you mentioned on the ridge below PB218.
This one has a flat top surface but I couldn't see the surface clearly as it's too heavy. Therefore I am questioning whether this could be a direction slab which similar to the one near PB313.

Anyone knows whether this is
Anyone knows whether this is a direction slab? I just found it right next to the entrance of PB302.
