Ishi, last member of the Yahi tribe, known as the "last wild Indian" (a Stone Age man), would be the first guy I would love to share a camp with - in any situation - survival or otherwise. Ishi was truly a "celebrity" - a household name in America and, later in Europe - after he was discovered in Oroville, California, and later brought for study to the University of California and, later employed at the museum there. Ishi became good friends, hunting partners, with Saxton Pope (of Pope and Young Club fame). Much credit goes to Ishi for bringing us to a better understanding and appreciation of primitive archery and, primitive survival skills used by the early Native Americans here in the West. Ishi was the ultimate and consummate survivalist with little to no exposure to the outside world.
I had the rare privilege, years ago, to be given a private tour of the Pope and Young Museum by Glen St. Charles. Glen allowed me to hold and inspect a number of the arrows, arrowheads, bags, tools, bows, etc., that Ishi made himself. The quality of Ishi's tools were nothing less than impressive. Only a true survivalist could manufacture and use these tools to the degree that Ishi did. Unlike Ishi, the rest of us need the modern world to supply most of our survival needs. Having studied Ishi for some time (his life and skills), in one way or the other, he is in my thinking and presence when I am on the path-less-traveled.
