lol - yah, I still got an old copy of Olsen's "Outdoor Survival Skills" back in the early 80s; it was the basis of a wilderness survival/naturalist course offered at a local Jr. College. Redford wrote the intro to the book and sourced Olsen for the Jeramiah Johnson film; the early seventies spawned a lot of environmental awareness new age revival of native wisdom which Redford touches on in his intro. I'm sure he was interested in encouraging a healthy respect of nature and people who live in appreciation of her... At the time I imagine the book may indeed have been "the finest of its kind" - its got a lot of good basics and is illustrated with lots of b/w photos (kinda rare at the time, I guess). I'm not an expert, but the books a fine addition to a basic wilderness survival/primative skills library, though John McPherson and Paul Campbell's books have far exceeded it, imho.
