For many years, I have had a copy of the book Outdoor Survival Skills by Larry Dean Olsen. Recently I wrote an article and stated that most people would die of slow starvation if they attempted to live solely of what they could gather from the wilds. Well he is an exception to this rule. He has spent most of his life teaching the ways to survive in the western U.S.
While teaching at wilderness survival courses at BYU, he took thousands of students on survival trips in the desert. The students were only allowed to take the clothes on their back and often stayed out weeks with him. He has lived for extended periods relying totally on techniques used by the Native Americans prior to the coming of the white man. This included making his stone knifes and other tools. He relied on no modern tools.
He wrote the book Outdoor Survival Skills in 1967. It is now on its sixth edition. This is a book that you should have in your library. While no book will teach you the skills to survive, only time and experience will do that. This book will lead you down some interesting paths if you want to learn primitive survival skills.
Even if you plan to bug in with a deep larder of supplies this is a book worth having. The information on snares and edible plants can supplement your food supply.
After following his career for many years, I recently had the chance to meet him and I was not disappointed. He attended a class I taught and his comments and insight were excellent. He is a fine gentleman and a real mountain man of the old school. If you ever get a chance to meet him, do it. In the mean time get a copy of his book and study it.
