I've not heard of a "Dead" cavern - and as far as I can ascertain "spelunking" is not recognised except perhaps as American-only slang abuse of novices or dilettantes. The proper word is "caving" throughout the English-speaking world.
As for the "dead cavern", I wonder if this what is also, at least in Britain and Europe, called a "Fossil" or "Abandoned" series; i.e. one that has been left high and dry by its formative stream diverting to a new, lower course or vanishing altogether.
Dead Wind Cavern is located near Primm Pass and is south of the Repconn Test Site; past Harper's Shack.
No; there is a picture from the Cavern with Paul pretending to be dead.
Not really.
Spelunking
You use Dive to get to the cavern and if I'm guessing right, the part that you're at is where it comes to a dead end. You simply press A and you will resurface.
