Re: [Texascavers] LED Flashlight review

[Charles Loving via Texascavers]

That was where Clark said Santa left presents in all the tents. And when we
went back to get the trucks they were surrounded by these narcos with lots
of guns but they were amazeed to find a bunch of gringos in the jungle in
wet suits. Too loco to kill or hold for ransom.

that the burned my fingers.

[Texascavers] UT Grotto Meeting - Dec 6

[Aubri Jenson via Texascavers]

Greetings, cavers!

At the UT Grotto meeting this week Wednesday, Greg Passmore

of
Passmore Lab, (http://www.passmorelab.com) will explain how Virtual Reality
imaging can be used to represent caves. He provided a demonstration at TCR,
so if you missed it or have questions, you should come see it! Pictured
below is a 3D rendering of Natural Bridge caverns in San Antonio, TX.



​


The presentation portion of the grotto meeting will be live streamed via
Periscope https://www.periscope.tv/utgrotto at approximately 8:30pm CST
(the actual time will be announced via Twitter @UTGrotto).

***

The meeting is at 8:00pm in Burdine Hall 212. Follow this link to a map of
where the building is located on the University of Texas campus:
http://www.utexas.edu/maps/main/buildings/bur.html


For information on Underground Texas Grotto activities, please see
www.utgrotto.org

Gather at Sao Paolo's on San Jacinto Blvd before the meeting for Happy
Hour. This is the best place to park and meet folks walking over to the
meeting. After the meeting we continue with the decades long tradition to
reconvene for burgers, beer, and tall tales of caving at Posse East!
www.posse-east.com 

See you there!
Cheers,
Aubri Jenson
UT Grotto Vice-chair

I was wondering if anyone had experience or techniques for extracting bailing wire plugs from a sinkhole ?

We know where the really good leads are on a ranch because the rancher that previously owned the property threw bailing wire into the really nice sinkholes to plug the holes up.
We have looped chains through the bailing wire and pulled plugs out of several sinkholes successfullyand found several new caves.

The "plugged" sinks are upstream of a very large cave in the recharge area.

But one of the best sinkhole leads has us mystified. 

The bailing wire is rusted and fragile. And there is significant organic matter captured in the wire mat. So the previous technique is not working.

We have several untested ideas. 

But thought someone might have experienced this before. Any ideas ?

Weave tubular sling through it and pull with man-power or a come-along. 
Keep repeating as needed.
