Blehm looks at the uber backcountry ranger Randy Morgenson. In his 28th summer in a dismally paid, and little appreciated job, Morgenson, the nearest thing to John Muir in his neck of the National Park Service, vanished. Blehm looks at this very interesting fellow, no simple mountain man. In fact Morgenson was friends with Ansel Adams, who advised him on one of his passions. Guess which? He was also friends with Wallace Stegner, who offered his wisdom on Morgenson’s writing. Blehm looks not only at Randy’s personal relationships, his failing marriage, his affair, his friendships, his love of the outdoors, the beauty to be found there, but at the role of rangers and how society supports, or does not support them. We also learn much about the ranger life, the parks in which Randy worked, the challenges rangers and park visitors face. This is a pretty good book for those interested in the outdoors, mountaineering, living close to nature. It might not do much for those who do not have an interest in that genre.
