the long version

"Two veterans of Sierra Nevada wilderness chronicle the first comprehensive history of fatal misadventures in Yosemite National Park from the time of the 1849 'discovery' of Yosemite Valley up to visitors falling off its giant waterfalls in the 21st century. The accounts of the nearly 900 people who have met untimely deaths in Yosemite offer the most astounding array of adventures, misadventures, history, and life-saving lessons between two covers"--P.
