2 Big 2 Fail

I think I would be mindful of the fact that there could be hazards down there and be prepared for them. Some that come immediately to mind are unstable ledges and possible entanglements. You don't know what sort of cables might have been left behind. Or what natural supports and abandoned equipment might have deteriorated over the years. Nothing you can't deal with, but I would be inclined to treat it sort of like a public safety dive in some ways, perhaps having a more elaborate buddy function than normal, a very conservative air use plan, and a safety diver or two standing by with extra air, tools etc. on the surface. It would be unfortunate to have a potential dive site closed to diving on account of a problem during the exploration. I would at least take more than usual precautions until you know more about the general nature of the place.
Quarries sometime have interesting surprises. They are naturally attractive to criminals wishing to dispose of various vehicles, safes, and inconvenient criminal associates.
