Veteran ski writer Porter Fox captures the 8,000-year-old sport of skiing, the miracle of snow and the truth of how climate change could wipe out both in the next 75 years. The narrative follows the unlikely rise of skiing from prehistoric Norwegian hunters to nobility in the Alps in the 1800s to present-day freeriders on the vaunted slopes of the Rocky Mountains. Fox talks to alpinists about the allure and mysticism of the sport and to scientists about climate change and its effect on snowultimately finding a story far larger than the demise of skiing. Fox uses primary interviews and evidence, mixed with scientific studies, to explain exactly how and when the Great Melt will play outand the groundswell that is rising up to stop it. DEEP provides firsthand accounts from skiers and scientists who are mapping a way to mitigate climate change, reduce human impact on our planet and repair the water cycle. As it turns out, their efforts to save snow and ice might end up saving the world.
