By Anmar Mirza, NCRC National Coordinator March 25, 2015 What do you do when you or someone you are caving with gets stuck? Not stuck like, "If I wiggle just right or relax then I can get out" kind of stuck. We are talking about the "We have tried everything and now don't know what to do" kind of stuck, the "Try not to panic ……should we call for help" kind of stuck. Do you know how to rescue yourself or someone else from an entrapment situation? This introduction to extrication will better prepare you to respond to this situation.
By Eddy Cartaya & Brent McGregor Febuary 17, 2015 Entering the fifth year of documenting the largest glacier system in the lower U.S., expedition leaders Eddy Cartaya and Brent McGregor are watching volumes of ice collapse from the walls and ceilings of giant borehole passageways penetrating into the Sandy Glacier on Mt. Hood. The cave ice is quickly being transported down a chain of rivers to the Pacific Ocean. There is no question at this point that our maps, data collections, and photographs will soon be all that is left of this spirited system of glacier caves that once stood so strong and powerful. The story of the Sandy is not new, but rather is echoed across the planet: a fateful realism that our glacier/ice caves are losing ice at an accelerated pace. If you enjoyed this presentation by Eddy and Brent, you will love Requiem of Ice, a video about Sandy Glacier, on Vimeo. Tracer Testing (Dye Tracing) in Karst Aquifers By Geary Schindel February 4, 2015 Tracer testing (dye tracing) is a very powerful tool to investigate groundwater flow paths and time of travel in karst aquifers.
Tracer testing can be used to define karst groundwater basins, the relationship between surface activities and water resources, identify source water protection zones, and develop realistic spill response plans. This presentation discusses common tracing methods and dyes, potential liabilities, and interpretation of results. By Rebecca Segrest January 27, 2015 Did you know that you or a fellow caver could get hypothermia even in a "warm cave"? Did you know that recognizing the UMBLES could save your life, or someone else's? In this Webinar, Rebecca Segrest will discuss the prevention and recognition of hypothermia in cavers, and how it may be treated in a cave rescue situation. Rebecca began caving in 1999, while studying at Berry College. In 2001, she became involved in rescue with the Chattanooga-Hamilton County Rescue Service. In 2008, she became an instructor with the National Cave Rescue Commission (NCRC). She is a Registered Nurse who maintains an ACLS, BLS, and a BLS instructor certification through the American Heart Association, and who specializes in the Cardiovascular ICU. Rebecca's fulltime job is as a SPRAT Level 3 Regional Manager for Over the Edge.

The 270-meter cave is home to the some of the oldest known painted art in the world at over 36,000 years old. The Paleolithic art in the cave, arguably some of the most magnificent in the world, was declared a World Heritage site by UNESCO in 1985. Charles touches briefly on the other Paleolithic art caves of Northern Spain, an additional 17 of which were added to the UNESCO World Heritage site designation in 2008.
George Veni November 18, 2014 About 25% of the US and the planet's land surface is karst. Karst areas are the world's most diverse, fascinating, resource-rich, yet problematic terrains. They contain the largest springs and most productive groundwater supplies on Earth. They provide unique subsurface habitat to rare animals, and their caves preserve fragile prehistoric material for millennia. They are also the landscapes most vulnerable to environmental impacts. Their groundwater is the most easily depleted and polluted. |
