What is the author's style in One Man's Wilderness: An Alaskan Odyssey by Sam Kieth?

Sam Keith, author of "One Man's Wilderness, An Alaskan Odyssey" writes this book from daily journals of Richard Proenneke that record his Alaskan wilderness experience. Keith is a Cornell University English graduate, who lived in Alaska for over three years before beginning his writing and teaching career in New England. He spends two weeks living with Dick Proenneke in his cabin during this project. The book was originally published in 1973 to record Dick's cabin-building and other experiences beginning in 1967. This book is the account of Sam's respected and dedicated friend who he met in 1952. Dick is skilled from his work as carpenter, diesel mechanic, sheep rancher, heavy equipment operator and commercial fisherman. After six months of being bedridden from an illness, Dick is obsessed by testing and challenging himself. He relocates from Iowa to test and prove himself in an unspoiled, Alaskan wilderness adventure.
