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.

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. (55:31) Download a copy (161 MB)

Relive the discovery of Altamira Cave in Cantabria, Spain through its discoverer, Marcelino Sanz de Sautuola. 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.

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.
