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.

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.

I have a hot-shoe adaptor for my Nikon D50 which causes it to function

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

My daughter's Olympus waterproof/shockproof camera couldn't withstand

There is probably some cave passage where you don't want to drag photo

might come in handy there.

Hi!
I use the Pentax Optio too (but the W30). I think it's very good for
in-cave use, it's waterproof and relatively rugged (I use a neoprene
sleeve too) and compact enough that often I just leave it hanging from
my neck (tucked in the suit), ready to snap then next picture. And it
doesn't have a moving lens cover or lens, which tend to have a gritty
death in caves.
At the International Congress in Kerrville, Bill Frantz talked about the
"Always Ready" photography kit, which is pretty much this setup, but
adding a flash and Firefly in a small clear Pelican box.
The Pentax Optio is nice for caving, but I think that Canon has better
picture quality. The PowerShot D10 would be great, but it's bulkier, so
it's not a comfortable camera for leaving around your neck.

Before we got the Canon PowerShot D10 we used a Pentax Optio
WP, which was the first model in that line from several years
ago. It performed well but the Canon seems superior. Of course
there have been many upgrades since the original WP, so I can't say
how the latest models compare. (There's now a W80, which is 12 MP,
same as the Canon.) One of the nicest things about the Canon is that
the lens protrudes from the rest of the camera body. While this
makes the camera bulkier, it also somewhat shields the lens from more
direct light of the flash, and that greatly reduces the white dots
that plague photos with an on-camera flash when there is mist or dust
in the air.

To the best of my knowledge, no dye tracing has been conducted in west
Texas. There are several traces I would love to do (and I've given
Sorcerer's Cave a lot of thought in this regard), but logistical details
would make most tracing in this area a significant effort.
For the most recent summary on the geology of caves in west Texas, and Texas
as a whole, look at pages 200-210 of Caves and Karst of the USA, which was
part of registration packet at the ICS. Pages 205-206 discuss Goodenough
Spring, but information on the Stockton Plateau, starting on page 203, is
related and interesting to consider. If you weren't at the ICS or opted out
of buying the book, it is available from the NSS Bookstore for $50:

Cavers, please start looking through your garages, storage units,
attics, sheds, and basements (for the few of you lucky enough to have
one!) for cave and camping gear, art items, fine foods or alcoholic
beverages, or anything else cave related or that would be appreciated by
other cavers. We are having another fund-raising auction this year at
the TSA Spring Convention, on Saturday evening after the banquet. In
previous years your generous contributions (and generous bidding!)
helped us pay off the property with Punkin Cave and Deep Cave in Carta
Valley, Texas. The TCMA is actively looking for additional caves to
purchase, and your contributions will help buy caves for cavers. Please
send me a short email if you have anything to donate, and I'll start a
list. You can bring the items directly to the TSA Spring Convention in
Cedar Park, unless you can't make it that weekend and want to make other
arrangements with me. My lovely assistants and I, as well as the rest
of the hard-working TCMA team, hope to see a record crowd this year. We
promise to make it entertaining if you promise to be free in both your
item donations as well as your bids. :-)

Tim,
The gas that caused the accident could be any number of different gases.
Methane, carbon dioxide, carbon monoxide, hydrogen sulfide, or just lack of
oxygen. Methane is usually colorless and odorless and would be difficult to
detect. It is flammable and explosive in the right mixture of oxygen.
Generally, it will displace oxygen and will naturally decompose to carbon
dioxide and water. Hydrogen sulfide (H2S) usually smells like rotten eggs and
is very toxic and also flammable. It also gives off a smell of rotten eggs.
I'm not sure that they would have gone into the mine if it smelled real bad.
Then again, you do become desensitized to H2S. Carbon dioxide has been well
discussed in Texascavers and can act as an asphyxiant and is also toxic. It is
a common mine gas and in the eastern US coal fields is called blackdamp and is
probably the most likely cause of the problem. Then again, if there as a fire
in the mine or cave, this could have resulted in carbon monoxide poisoning.

If you have no interest in Facebook, please ignore this
message.
Many of you are on Facebook now. I have a slow internet connection,
and in the past few days, Facebook has been worthless.
If anybody out there is having similar issues, you can resolve some of
them by changing the 3 letters "www" to "lite," in the address bar.
This should switch you over to Facebook Lite.
Below is an example of an event on Facebook Lite and below that, a
different version of the same
event on regular Facebook:
The lite version:
http://lite.facebook.com/events/1st-Annual-East-Texas-Cavers-Cookout/356560204044/
The regular version:
http://www.facebook.com/event.php?eid=299417037079
Facebook Lite is so stripped down that most Facebook users will find
it useless. But it does allow
you to check your messages, and see your Friends list.
One of the great things about Facebook is the way
it helps event planners organize an event. The only
problem with this tool, is that so many people are not
on Facebook, or don't use it regularly.
But with Facebook Lite, this feature is so stripped
down, that it is annoying to use. For example, I created the event
above, but it is not listed in my
events, so I can't directly access it. That seems
more like a bug, than a feature removal.
In Facebook Lite, you can't hide your friends. I
couldn't get the Chat function to work. "News Feed"
is called "Stories."
It does not have games, and doesn't suggest friends,
and has only one advertisement.
It does not allow you to see regular Facebook events
like the 2010 TSA Spring Convention.
An improvement to Facebook would be for
the attendee to be able to click on a box that lets them see a
watered-down version of the event, that just shows confirmed guest,
and the date and address of the event, meaning a lite version without
having to create a separate lite version of the event.
And the same goes for many of the other features of
Facebook. I don't think they need a separate lighter version, unless
it is designed just for smartphones.

Charles,
It is related to caving in the same way that all of the other caving related
equipment discussions on Texascavers are related to caving. This list
frequently contains discussions about equipment, including lights, cameras,
camping equipment, vehicles, etc., which cavers often use in caving related
activities. Cavers frequently use computers, operating systems, and
applications software, not only for accessing Texascavers, but also for a
variety of other purposes directly related to caving, including cave mapping,
3D cave modeling, editing of cave photographs and videos, presentation of
caving slide shows and video programs, editing and dissemination of caving
publications, collection and analysis of cave related research data, and
coordination of caving related activities. The information referenced in my
brief message about a new Windows 7 update could affect anyone using Windows 7
for any of these caving related purposes. Therefore, I believe it is directly
related to caving and is at least as appropriate for this email list as are the
numerous other equipment related discussions routinely accepted on Texascavers.

My oversight. You are right, you both did the hard part and completed the
survey. Bad air yes, but it probably was much worse before we blew good air
into the pit for an hour.

Just wanted to make you cavers aware that a new map of Lemons Ranch is now
finished and it will be at the TSA salone for viewing. The survey is complete
now and the survey footage totals 949 ft. with a depth of 104 ft. This is the
third deepest cave at the park I am told. My thanks go to those who helped
with the survey. They are : Will Harris, Ronnie Harrison, Rafal Kedzierski, Ed
Spaulding, Scott Boyd, Bonnie Longley, Justin Menking, Kurt Menking, Kathleen
O-Connor, Mark Sanders, and Jessica Stevenson. There are two dig leads at both
ends of the cave but both are grim. Both are in bad air. We were able to
complete the survey by running 225 ft of 6" air duct down into the cave to blow
out the high concentrations of CO 2. We plan to survey other bad air caves as
long as bats are not present in the caves.
Happy Caving !

Absolutely!
Without Marks air blower and 200ft of tubing into the cave, the surveying
would not have been possible at all. It worked remarkably well. I was
impressed.

Absolutely!
Without Marks air blower and 200ft of tubing into the cave, the surveying would
not have been possible at all. It worked remarkably well. I was impressed.

My oversight. You are right, you both did the hard part and completed the
survey. Bad air yes, but it probably was much worse before we blew good air
into the pit for an hour.

Actually, Matt Zaldivar and I surveyed the final depth of Lemon's Ranch. Mark
and Rafal recorded the data. It was bad air, very muddy and a ton of fun!

Just wanted to make you cavers aware that a new map of Lemons Ranch is now
finished and it will be at the TSA salone for viewing. The survey is complete
now and the survey footage totals 949 ft. with a depth of 104 ft. This is the
third deepest cave at the park I am told. My thanks go to those who helped
with the survey. They are : Will Harris, Ronnie Harrison, Rafal Kedzierski, Ed
Spaulding, Scott Boyd, Bonnie Longley, Justin Menking, Kurt Menking, Kathleen
O-Connor, Mark Sanders, and Jessica Stevenson. There are two dig leads at both
ends of the cave but both are grim. Both are in bad air. We were able to
complete the survey by running 225 ft of 6" air duct down into the cave to blow
out the high concentrations of CO 2. We plan to survey other bad air caves as
long as bats are not present in the caves.
Happy Caving !
