My annual birthday-month fund-raising drive for Behind the Black is now on-going. Not only do your donations help pay my bills, they give me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.
Please consider donating by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below.
Regular readers can support Behind The Black with a contribution via paypal:
If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage. And if you buy the books through the ebookit links, I get a larger cut and I get it sooner.
From an email sent out by Ukrainian caver Alexander Klimchouk, received today:
Pavel Rud’ko of Krasnoyarsk (Rissia, Siberia) has reported the success of the recent expedition of Krasnoyarsk cavers to the Sarma Cave, Arabika Massif, Western Caucasus. The cave, previously explored by cavers from Krasnoyarsk and Irkutsk to -1570 m, has now been made almost 200 m deeper, to reach depth of -1760m and become the second deepest cave in the world.
The expedition led by Pavel Rud’ko has been carried out between September 1st – October 7th, 2011. The main branch has been pushed to -1760 m after breaking through a narrow meander at the old bottom. Many side and ascending passages in other parts of the cave have been also explored. The expedition performed systematic temperature measurements, and speleobiological and microbiological sampling.
With its new depth figure, Sarma surpassed the Illjuzia-Mezhonnogo-Snezhnaya system (-1753 m), located in the nearby Bzybsky Massif, and became the second deepest cave in the world, following Krubera Cave (-2191 m) located in the same massif. Thus, the western Caucasus now hosts three deepest caves in the worlds, two of them in Arabika Massif and one in Bzybsky Massif.
