Uncertain Years PDF Download

"Uncertain Path is a must read for wilderness and parks lovers who also know that climate change must be addressed if we are to be good stewards of our natural heritage. Bill Tweed is leading us down the right trail just in time." —Carl Pope, Chairman, Sierra Club "Author and naturalist Bill Tweed, like Muir, assumed that large, wild parks and wilderness areas could protect themselves, if we just let nature run its course. But on a hike along the John Muir Trail Tweed comes to the realization that, 'Natural' processes cannot lead reliably to 'natural' results in a world where climate change, global population, and habitat fragmentation have changed the operating rules...' It is a vital lesson we must all learn and act on—quickly and decisively—if we want to pass on a wild heritage to future generations."—Bruce Hamilton, Deputy Executive Director, Sierra Club “Bill Tweed has that rare combination of deep historical knowledge and even deeper passion for the national parks. He displays them both in Uncertain Path, a journey through the High Sierra that looks at the past and potential future of these American treasures. I can’t think of a better trail guide.”—Dayton Duncan, author of The National Parks: America’s Best Idea "This is history from the inside, intimate and provocative, growing from both the trail and from forty years of living with the Sierra Nevada. Younger generations are redefining the value of national parks just as global climate change transforms the very ecosystems that parks preserve. Tempered by managing parks and wilderness and people, Bill Tweed measures these sweeping changes with a clear eye. With deep concern and courage, he offers a sober vision of how to manage our national parks in the 21st century."—Stephen Trimble, author of Bargaining for Eden: The Fight for the Last Open Spaces in America "After nearly four decades as a park ranger revealing the secrets of nature to the visiting public, Bill Tweed took a 240-mile walk through the Sierra Nevada and took us along. Nothing escapes his loving attention, and like John Muir, Tweed sees each thing as connected to everything else, drawing rich conclusions about the future of the national parks. By all means, don't miss this trip."—Jordan Fisher Smith, author of Nature Noir "Bill Tweed's Uncertain Path is an invitation to the high country of the Sierra Nevada and also public land issues and philosophy. It's a wise and challenging exercise with a grand broad view."—Gary Snyder, author of The Practice of the Wild: Essays
