Field NotesThat water from your tap may have started as snow falling on a granite peak somewhere high in the Sierra Nevada. Ever wonder "how much" water is stored in that snow each year? Answering that question starts with a pair of backcountry skis and a heavy pack... Ever wonder who cuts those logs that fall across the trail deep in the back country? Using a cross cut saw is a traditional (and challenging) skill mastered by many backcountry rangers throughout the Sierra. Join Yosemite's geologist as he teams up with the park's climbing ranger to climb El Capitan, one of the world's largest granite faces. Thousands of years ago a gigantic rock fall likely released from high on El Cap's face. Exactly where and when are among the many questions Greg Stock is curious to answer. |
