Re: [Texascavers] a cave question

Using metal strips or tags was once a popular method of marking stations in Texas caves. You can still find them in some of the caves that were surveyed back around the 1960s. I still use colored aluminum tags for permanent stations that I want to easily relocate. Jerry. In a message

Re: [Texascavers] Carbon Dioxide and Low Oxygen in Texas Caves.

Elevated CO2 is a common occurrence in Texas caves with the highest levels typically being found in caves developed in the Ellenburger or Austin Chalk formations. Both of these formations have low permeabilities, and it is conjectured that this impedes the ability of CO2, once it accumulate

[Texascavers] caver music ?

Is this a French version of the Terminal Siphons ? http://musikplease.com/theant-sporto-kantes-speleology-11470 Whatever, it is they stole the idea from the old Buck Rogers movie ( 1979 ) http://www.youtube.com/watch?v=RHG29QjqYZ8&feature=related

[Texascavers] a cave question

I have a question, or questions. Do cavers still place numerical metal tags at caves? Do any caves still have the old metal tags around them ? My memory seems to recall seeing a round tag a little bigger than a quarter with a number on it at a cave I once went to. I can't remember if I saw that

[Texascavers] more new LED stuff

There are a bunch of new LED flashlights and headlamps to talk about, but the only one really interesting to me is this one: http://www.brightguy.com/products/Energizer_Night_Strike_Handheld_Light_3AA_ENSHH31L.php I played with it at Gander Mountain today. I think they wanted $ 77 for i

[Texascavers] Carbon Dioxide and Low Oxygen in Texas Caves.

Someone ought to post more on this subject because of the potential for Hazardous levels of Carbon Dioxide in many areas of Texas. We seem to have been blessed with a lot of karst (Ellenberger primarily) prone to generating high levels of CO2 in the warmer months. I can tell you that it can certa

Re: [Texascavers] carbide vs LED (attempt 2)

Very similar experience in Midnight cave about 12 years ago on an aborted trip. I was first down. It seemed awful dank from the beginning but near touchdown on the garbage pile, it got so bad I was having trouble breathing - I could "feel" hyperventilation coming on . (No CO2 monitor, no lighter

Re: [Texascavers] carbide vs LED (attempt 2)

The only time I ever rappelled into Deadman's hole, I had an experience like this. I went down slowly, expecting possible co2 because the caves in the Ellenberger in that area are known for it, but still, I was very surprised by how stratified it was. Where I stopped on rope when the air st

Re: [Texascavers] carbide vs LED (attempt 2)

While surveying a cave in southern Kentucky years ago, well decades ago, I developed a headache. After a few more shots down and into a room with a huge pile of rotting leaves, my carbide lamp started acting up. For some reason I climbed up high and onto a ledge to change carbide. The lamp still
