I didn't see the waterproof Pentax Optio W60 mentioned yet. I have had
mine now for a year and a half and keep it in a small belt pouch with
an extra SD card and battery in the small pocket. I picked it as my
light weight cave camera because it has a really nice close-focusing
ability plus the other more common features. I found a small imported
slave flash on e-Bay (~$15) with a choice of 1,2,3 or 4 trigger
flashes for use with digital cameras. It's apart now because I want to
move the slave sensor from the "front" to the "side" so it will be
more versatile for cave photography. Another caver modified a similar
unit that works well by moving the slave sensor to the "back" of the
flash. I prefer the selector switch, particularly when working with
other photographers, to the much more sensitive FireFly model because
it's hard to remember the programming sequence for the FF when you are
at the end of a long day in the cave.

The digital Firefly is designed to "count" the flashes and not trigger
the strobe until the focus/exposure pre-flashes are complete. It can
be programed for a various number of flashes based on the specific
camera you are using. The down side is that it has a long (10ish
seconds? Can't remember for sure) recycle time, meaning you cannot
take 2 pictures close together.
And be careful using olf school flashes with new digital cameras. The
trigger voltage on the old model 283/285 is over 200 volts, and many
of todays digital cameras (assuming you have a hot shoe to begin with)
cannot handle that much voltage. Check your camera specs. There are
newer versions of the 283/285 designed for digital cameras with a
lower trigger voltage.

Firefly makes a version of their slave that's designed to work with
digital cameras -- the timing on them is somehow different from film
cameras.
I have a hot-shoe adaptor for my Nikon D50 which causes it to function
with my Old Skool Vivitar 285, but with a point & shoot built in
flash, one of those digital Fireflys and one extra flash might not be
too much to tote with a compact camera.
The touch-screen seems worrisome, though. I thing it'd get pretty
dirty pretty quick.
My daughter's Olympus waterproof/shockproof camera couldn't withstand
the shock of being carted around in her book bag, so I wouldn't put
too much stock in them, either.

Here is a new camera that would easily fit in your cave pack:

I doubt the flash is bright enough for cave photography, but is any
pocket size camera?
There is probably some cave passage where you don't want to drag photo
equipment, like beyond the sump in Honeycreek. This camera
might come in handy there.
