Sorta related, I recently found a copy of Tom Brown's {i] "Guide to Wild Edible and Medicinal Plants"[/i], I had forgotten all about that guy.
Apparently he's still around and still running a survival school in New Jersey where according to Wiki he runs sweats and his version of Plains Indian ceremonies.
https://en.wikipedia.org/wiki/Tom_Brown_Jr.Wrote a book about "Healing the Earth" as recently as 2019.
Gotta admire the guy for pulling this all off
Wiki casts doubt upon the existence of his buddy's Lipan Apache grandfather, who ostensibly sent Tom off down that path.
Small world! Back in the 70's this figure was as remote to me back in NY State as anyone, turns out there's a bunch of Lipans in San Antonio, tho many off of any Tribal rolls, I've taught some of their kids. There coulda been a Lipan "Stalking Wolf" sixty years ago as Mr Brown claims I guess, especially if he was raised in Mexico.
