I’m sure that there’s plenty of “natural”light to guide the way, and zero chance of anything going badly… Mark’s brand of “faith,” driven by, among other things, the fact that we is perpetually 33 years old, should provide plenty of cover when it comes to a perilous situation like this…

And Carina, Mark is not going to “Wait” any more than you obeyed his request, the maneuver that sent you down the face of the waterfall…  But what Mark really needs is Batman’s utility belt!  There he would find an underwater breathing apparatus- the “Re-breather” along with a long cable with a hook  on the end that could be used to maroon himself under water…

Sorry Campers,  I was away a couple of days… the suspense of not knowing how little progress was being made was about driving me crazy!

Well, I see now that almost no progress has been made, other than to conjure up a few hackneyed expressions while applying some stilted dialogue…  Yea, Mark, what IF the hole is only a foot in diameter, huh? Huh??

I am nigh on speechless here…  this is where the plot leads us?  To a hole in a wall that can’t be seen but must be there because the flowing, rushing water is not filling up the cave?  Sort of like a Black Hole in Space that cannot be seen but we know is there because of its effect on visible things around it?

Go for it, Mark… you are probably right.  There’s nothing else to be done at this point…
