Abstract:
Brown W.A., Stafford K.W., Shaw-Faulkner M., Grubbs A. 2011. A comparative
integrated geophysical study of Horseshoe Chimney Cave, Colorado Bend
State Park, Texas. International Journal of Speleology, 40(1), 9-16. Tampa, FL
(USA). ISSN 0392-6672. DOI: 10.5038/1827-806X.40.1.2
An integrated geophysical study was performed over a known cave in
Colorado Bend State Park (CBSP), Texas, where shallow karst features are common
within the Ellenberger Limestone. Geophysical survey such as microgravity,
ground penetrating radar (GPR), direct current (DC) resistivity, capacitively
coupled (CC) resistivity, induced polarization (IP) and ground conductivity
(GC) measurements were performed in an effort to distinguish which
geophysical method worked most effectively and efficiently in detecting the
presence of subsurface voids, caves and collapsed features. Horseshoe Chimney
Cave (HCC), which is part of a larger network of cave systems, provides a good
control environment for this research. A 50 x 50 meter grid, with 5 m
spaced traverses was positioned around the entrance to HCC. Geophysical
techniques listed above were used to collect geophysical data which were
processed
with the aid of commercial software packages. A traditional cave survey
was conducted after geophysical data collection, to avoid any bias in initial
data collection. The survey of the cave also provided ground truthing.
Results indicate the microgravity followed by CC resistivity techniques worked
most efficiently and were most cost effective, while the other methods
showed varying levels of effectiveness.

I think we should get a group of cavers together and go see it dressed up in
gear, for fun.
Kind of like the Harry Potter fanatics whenever a new Potter movie comes out.

When the IMAX Amazing Caves movie came out years ago several of the Bexar
Grotto cavers met with the local IMAX theater and volunteered to do some
rappelling or Tyrolean traverse stunts on the nearby buildings. Several
options were discussed but ultimately the rope work was scratched. They did
however invite all local cavers to watch the movie for free before it was
officially released. They asked several of us to dress up in our gear for
several showings. It was fun and I got to see the movie several times for free.

We would need to decontaminate our gear after having sat in most movie
theaters though...

Logan,
Thanks for this great website info. HT was/is indeed a magical place. I would
like to visit it again if time (longevity) permits. I truly love the desert
country, hence my fascination with the Big Bend area. State Park or not, my
feelings are that rock climbing at HT should be restricted to areas of the
mountain void of rock art. All visitors should be searched to prohibit any form
of marking devices such as paints, markers, knives, sharp tools and even
carbide lights. These restrictions are necessary to protect this valuable
history and beauty from those among us who would desecrate it. Harsh? Hardly.
There are always a few who ruin it for all.
Fritz

Fritz, et al.
The Texas Beyond History website also has a great exhibit on Hueco Tanks! It
is a world class rock art site, first publicized in the book The Rock Art of
Texas Indians (Kirkland and Newcomb, U.T. Press, 1967) . When I went back
there on a project in 1999, TPWD had hired Evelyn Billo and Robert Mark to take
digital photographs of "all" the pictographs, and there are thousands of them
hidden away under hollow boulders, shelters, alcoves, you name it. Bob and
Evelyn were staying in the same motel as our crew, and one night they excitedly
called us to their room to see some of the photos. Bob had decided to
experiment with digital enhancement (when did PhotoShop come out?), and
discovered that many of the rock art panels suddenly exploded with images
unseen by the proverbial naked eye. You can see some of the results on:
Texas Beyond History Hueco Tanks website
http://www.texasbeyondhistory.net/hueco/index.html
[you'll even see some old photos of Ron Ralph, Don Broussard, Steve Zeman &
Dino Lowrey (with the basin metate), and me]
and on the Rupestrian CyberServices website http://www.rupestrian.com/
Hueco Tanks is also a world class bouldering site, and therein lies the rub,
quite literally. Thousands of boulderers from all over the world were spending
the winter there. Unfortunately, many of the pictographs are under overhangs
and other places that are also the best places to climb. Many of the
pictographs are very difficult to see, and were being heavily impacted, not
just by the boulderers, but by picnickers and gang bangers from El Paso and
elsewhere who were tagging the rocks with spray paint. The sparse vegetation
in the protected areas was also being wiped out. A classic problem with parks:
balancing the recreational opportunities with the cultural and natural
resources. Something cavers can certainly understand, with fragile caves such
as Lechuguilla, Caverns of Sonora, etc. So there were contentious public
hearings and angry letters to the editors from both sides. TPWD finally had to
limit the number of people who could be in the park at any one time, and
restrict or prohibit access to some of the more sensitive areas.
After the news came out about Bob & Evelyn's work, I remember seeing a post on
one of the climbing websites that said something like: "Oh great, now they're
telling us we can't climb in places where there's rock art you can't even see!
Reminds me of the current debates about how to deal with WNS. No easy answers.
Hueco Tanks is a magical place. If you're ever traveling to the El Paso area,
Carlsbad, or the Guads, it's worth a stop. Best to contact TPWD first to make
reservations.

on the north side of a range of low mountains and cliffs. We climbed around for
probably three or four hours looking in the many shelter caves and crevasses.
The ancient and colorful rock art was totally fascinating as were the rock
formations themselves. Of course, there was also graffiti, some of it from the
previous century. There was not another soul at this wondrous place known as
Hueco Tanks, but possibly a few ancient spirits.

I have my opinions but will leave it to those in authority to make the
decisions, which they will anyway. Assuming they make any decisions.

How much time do you think will have to pass before that spray paint tagging
becomes similarly protected and preserved as historically or archeologically
significant "rock art"? What are the least old graffiti examples you know of
that are now protected and preserved as being historically significant?
Just wondering,
Rod

I copied this from TagNet this morning, so the times are Eastern time.
National Geographic Caving Specials
Two television specials about caving will be shown on the National
Geographic Channel this Thursday evening, January 27. "The Real Sanctum"
is on at 9:00 pm EST and describes how the caving movie "Sanctum" was
filmed and created. The "World's Biggest Cave" follows immediately at
10:00 pm and is about Hang Son Doong, the cave featured in the January
2011 issue of the National Geographic Magazine.
