I was able to skim through the book "The Shamanic Powers of Rolling Thunder: As Experienced by Alberto Villoldo, John Perry Barlow, Larry Dossey, and Others" by Sidian Morning Star Jones and Stanley Krippner rather quickly, the book contains a lot of fluff filler that isn't specifically about RT (John Walter "Rolling Thunder" Pope).
Book contains stories from some frauds we know including:
Phillip Scott

http://www.newagefraud.org/smf/index.php?topic=615.0Several people say RT abused alcohol. And that he sized up all women as potential sexual partners. It is said that women were told that they could not stay at RT's camp unless they consented to sex.RT said he had a dream that Quetzalcoatl merged with him and gave him powers.
He supposedly could summon rain storms and thunder, cause a tornado to help a Shoshone youth be freed from prison, block his image from a photograph being taken without his permission, tame wild animals, exorcise spirits by having the target paint their face with black ash, make his snake ring glow and lift its head, heal, hypnotize, and see into people's souls.
Phillip Scott never met RT but says RT helped heal and guide him. Several other people claim long distance healing and visions from RT.
RT interfered in discovered ancient burials.
For the "healing" work he did on people he used North American herbs, Chinese herbs and also pharmaceutical samples that medical doctors gave him.
He was a huge hit in Germany.
His followers romanticized and made him a saint, they wanted to have unusual experiences and so they had them. They excused how he treated woman as a sign that he was a strong shaman.
Penny McKelvey AKA "Oh Shinnah Fastwolf" had a long term relationship with one of his sons, Buffalo Horse. She makes excuses for RT's behavior but it sounds like she also stayed away from being alone with him. She says she eventually had to distance herself from him because of how he treated most women.
Sidian chose his name as a form of "obsidian", an obsidian scrying mirror. He sees himself as an occultist, potential cyber shaman, He only met his grandpa a few times. Once RT handed him a tomahawk and he thinks that means he is to carry on the family traditions.
