Okay, please confirm, are you going to check the rest of the structures here (there are some tombs) or make your way toward your best guess at which way will lead further downward.
Here's the map of the area:

You guys have not been to 0.
You guys have been to 1, didn't jab the jewel eyes out.
You guys walked around 2, but didn't make any special effort to find a secret entrance.
You guys have been to 3, didn't find much.
You guys have looked at 4, but have not actually walked on it or looked closely.
5-8 have been seen from a distance.
You are currently at 9, and there doesn't appear to be much else to figure out or see.
Don't mistake all of those words as an indication there's anything important here, I'm just bored and out of beer. Moving downward is your best bet on making shit happen or progressing the story most quickly.
