Daughters of Radon - following the Natural Trap thread The monitoring in Carlsbad started around 1975 or 1976. The discovery of high levels of radon in Carlsbad Caverns caught all the federal cave management folks off guard. The Daughters of Radon concern resulted in the first ever Cave

Re: [SWR] Natural Trap: CJ Rushin 1972 work

From CJ Elron (nee Rushin): I did my Master's research in Natural Trap Cave in 1972 (Barry Fuller was on my crew). There is a copy of the resulting thesis at the University of Montana, and there was a copy at the BLM field office in Cody. Natural Trap was gated not long after I finished my

Re: [SWR] BLM reopens Wyoming's Natural Trap Cave

Don't know. I heard rumors that the reason that Holy Sheep was open only to one trip a year was because the geiger counter had registered either max, or close to it. Paha Sapa Grotto in Wyoming would have a better idea, but I was hoping that someone here, including Donald Davis, could give some

Re: [SWR] BLM reopens Wyoming's Natural Trap Cave

So I've been debating on if I should reply to this or not because what seems like a simple question has a very complicated answer. First, I don't know anything about the cavers mentioned but I do know about radiation and legal exposure limits. Geiger Counters are all different and have

Re: [SWR] BLM reopens Wyoming's Natural Trap Cave

Greetings fellow Cavers., Just an FYI to everyone, I've made a change to the mailing list software on the reply-to section. It used to default to the user who sent the email, and people had to hit reply-all to send back to the mailing list. This now defaults to the list, and while

[Texascavers] GPS recommendation?

I¹ve decided it¹s finally time to abandon my luddite ways and join the GPS generation. Any recommendations on the best model for a caver/backpacker/river runner to buy? And is any particular model or brand better for use in Mexico? Thanks, Frank ___
