Here's one that looks pretty good. They indicate that it's rugged and water
resistant. Good up to 230 feet.
Anyone used one?

Last chance to go caving tomorrow. William and I will be there at 9:30 and
you can come anytime as we hope to dig for several hours. Give me a call if
you get lost.

Central Texas Cavers,
Bill Russell has mostly recovered from his stroke and is ready to go caving.
Please join him at Ruby Ridge, Hays County, Monday morning, May 24, between
9 and 10am to celebrate. We will be cleaning out a vertical shaft that has
been filled with small rock, then open up big passage (hopefully). Bring
appropriate tools, clothing and gloves. I will bring a ladder, shovel and a
wheelbarrow.
Please let me know off-line if you can attend, then just show at the cave.
The address is 1397 Ruby Ranch Road, Buda. Park on the road or the pipeline
ROW.

Did you get a response, Joe?
We're going in October and I could use one, as well.
Thanks,

Texas Camp
Hey -
A bunch of us are headed to the High Guads over memorial day (with
permits). It has been 5 or 6 years since I've done the drive so I would
love a good road log if anyone has one to share.
Many thanks!

Since this is karst related, I thought that I would send it out to the email

Coal-mine drainage as a driver for carbonate dissolution; deciphering the
balance between acidity, alkalinity, CO2 and karst processes
Acid mine drainage - formed when pyrite oxidation releases sulfuric acid and
iron - is a common sight in the coal-mined regions of Appalachia. However,
when carbonate layers are present in the coal sequence, the mine drainage may
be alkaline rather than acidic. In flooded mine systems, elevated CO2
pressures can occur as the sulfuric acid from pyrite oxidation drives carbonate
dissolution while metal precipitation consumes the generated alkalinity. These
settings provide an interesting, anthropogenically-caused analog to karst
systems where sulfuric acid drives cave formation.
Biography: Dorothy Vesper
Assistant Professor of Geology, West Virginia University
Dorothy Vesper applies her interest in inorganic geochemistry to both beautiful
karst springs and not-so-beautiful contaminated sites. She has a BS degree in
geology from Juniata College, and MS and PhD degrees from The Pennsylvania
State University. For the 10 years between the two graduate degrees, Dorothy
worked for consulting firms in the Boston area. A karst project in
Kentucky-Tennessee convinced her to come back to school for the third and final
round. Her current karst projects focus on conceptual models, protection and
sustainability of water resources in the structurally-complex Ridge and Valley
Province. In her spare time she studies metal geochemistry at mining-related
sites.
