Travels in Alaska, which John Muir was working on at the time of his death, is based on journals Muir wrote during his visits to Alaska in 1879, 1880, 1881, 1890, and 1899. From the moment he embarked from San Francisco in May, 1879, "off for icy Alaska," Muir sensed he was on an extraordinary adventure. Venturing on foot, by canoe and dogsled, he experienced equal excitement discovering an unfamiliar species of flower, bird, or tree, or the spectacular Glacier Bay -- all of which he conveys with consummate artistry. Here also is a record of such harrowing experiences as rescuing his companion while the two hung over a thousand-foot precipice and narrowly escaping. death between grinding walls of glacial ice. Travels in Alaska culminates with Muir's vivid description of the "supreme, serene, supernal beauty" of Alaskan auroras observed during his penultimate trip in 1890. "Men like Muir (Robert Marshall was another) continue for us the spiritual reclamation of North America. At their keenest, they evoke for us something of the freshness of an hour and a day when, before the intervention of culture, men saw the world for the first time as something wonderful and new." - John Haines, from his Foreword About the author: John Muir (21 April 1838 - 24 December 1914) was a Scottish-born American naturalist, author, and early advocate of preservation of United States (US) wilderness.

His activism helped to save the Yosemite Valley, Sequoia National Park and other wilderness areas. The Sierra Club, which he founded, is now one of the most important conservation organizations in the United States. One of the most well-known hiking trails in the US, the 211-mile John Muir Trail, was named in his honor. Other places named in his honor are Muir Woods National Monument, Muir Beach and Muir Glacier. In his later life, Muir devoted most of his time to the preservation of the Western forests. He petitioned the U.S. Congress for the National Park Bill that was passed in 1899, establishing both Yosemite and Sequoia National Parks. It was due to the spiritual quality and enthusiasm toward nature which he expressed in his writings that he was able to inspire his readers, including presidents and congressmen, to take action to help preserve large nature areas. Muir's biographer, Steven Holmes, states that Muir has become
