20 Extreme Adventures For Spelunkers and Cavers


Where the Mountain Casts Its Shadow: The Dark Side of Extreme Adventure Book Description

Without risk, say mountaineers, there would be none of the self-knowledge that comes from pushing life to its extremes. For them, perhaps, it is worth the cost. But when tragedy strikes, what happens to the people left behind? Why would anyone choose to invest in a future with a high-altitude risk-taker? What is life like in the shadow of the mountain? Such questions have long been taboo in the world of mountaineering. Now, the spouses, parents and children of internationally renowned climbers finally break their silence, speaking out about the dark side of adventure.
Maria Coffey confronted one of the harshest realities of mountaineering when her partner Joe Tasker disappeared on the Northeast Ridge of Everest in 1982. In "Where the Mountain Casts Its Shadow," Coffey offers an intimate portrait of adventure and the conflicting beauty, passion, and devastation of this alluring obsession. Through interviews with the world's top climbers, or their widows and families-Jim Wickwire, Conrad Anker, Lynn Hill, Joe Simpson, Chris Bonington, Ed Viesturs, Anatoli Boukreev, Alex Lowe, and many others-she explores what compels men and women to give their lives to the high mountains. She asks why, despite the countless tragedies, the world continues to laud their exploits. With an insider's understanding, Coffey reveals the consequences of loving people who pursue such risk-the exhilarating highs and inevitable lows, the stress of long separations, the constant threat of bereavement, and the lives shattered in the wake of climbing accidents.
"Where the Mountain Casts Its Shadow" is a powerful, affecting and important book that exposes the far reaching personal costs of extreme adventure.

Fragile Ecosystem

types

Over tens of thousands of years, water that seeped through cracks in a cave react to minerals and carbon dioxide to form speleothems. Most of these rock formations are named after their resemblance to man-made objects. The six most commons types are flowstone, stalagmites, stalactites, column, drapers, and straws. However, the ecosystem in a cave is extremely fragile. What took thousands of years to form can be damaged by the slightest touch. Some can even be irreparably damaged by something a simple as being breathed upon. Cave conservation is all important to keep the underground playground as unspoiled by mankind as possible.

Eye Candy – Luray Caverns

There are five main rules to keep in mind before cave diving. Training, do not attempt a dive beyond your experience level. A guide line should be maintained at all times in the event a silt out occurs so divers can follow the line back to the underwater cave entrance. Divers are advised not to exceed excessive depth and to keep in mind the changes such depths can cause to their gas mixture. Even among fully trained and experienced cave divers, not paying attention to depth is the number one cause of fatality. The rule of thirds, indicating a diver should save one third of their air for a team member in case of an emergency. Under no circumstances should a dive be attempted without each cave diver having three different light sources. These rules can be remembered with the mnemonic Thank Goodness All Divers Live, or known as The Good Divers Are Living in the UK; training, guide line, depth rules, air management, lights.
