Secrets Of The Mysterious Valley

Rate this book
No other region in North America features the variety and intensity of unusual phenomena found in the world's largest alpine valley, the San Luis Valley of Colorado and New Mexico. Since 1989, Christopher O'Brien has documented thousands of high-strange accounts that report UFOs, ghosts, crypto-creatures, cattle mutilations, skinwalkers and sorcerers, along with portal areas, secret underground bases and covert military activity. This mysterious region at the top of North America has a higher incidence of UFO reports than any other area of the continent and is the publicized birthplace of the “cattle mutilation" mystery. Hundreds of animals have been found strangely slain during waves of anomalous aerial craft sightings. Is the government directly involved? Are there underground bases here? Does the military fly exotic aerial craft in this valley that are radar-invisible below 18,000 feet? These and many other questions are addressed in this all-new work by one of America's top paranormal investigators. Take a fantastic journey through one of the world's most enigmatic locales!

Interesting but badly edited, Chris O'Brien wrote a mishmash of various oddities and mysteries from the San Luis Valley in Colorado over the years, UFO sightings, miraculous saints, lost mines, paranormal stuff and cattle mutilations dominate. He needed to whittle it down to about a third of what he has here and have someone edit it. Basically this book is several hundred pages of rambling, repetitive stories and theories with little evidence to support them. Sometimes riveting, sometimes boring.

This book will most certainly make you look at the world around you a lot differently and for that reason its worth the read, but the constant grammar and spelling errors made it a real slog if I'm honest, I'm not usually super picky regarding grammar, but when its every other page then it starts to become a problem. In O' Brien's defense he certainly worked hard on his research here and even touches on skin walker ranch before it become mainstream stuff. O'Brien simply doesn't get enough credit for this. Personally it was a book between books, in essence a go back to book after a chapter or 2. A good reference for some of the most hard to find compiled remote unexplained cases, if you can get through the difficult writing style of O' Brien. Below average pick up and put down for me.👍

This book is part autobiography and part an account of investigations of a variety of unusual events/sightings in the San Luis Valley of Colorado.
The book covers the period 1993 to 2006, and documents UFOs, balls of light , unmarked helicopters, Bigfoot sightings and, nastiest of all, mutilated animals, mostly cattle. It is to O'Brien's credit that he doesn't instantly blame aliens , but instead looks at all these occurances in chronological order, thereby allowing the reader to draw their own conclusions.

Lots of research and stories about mysteries in the world's highest alpine valley. Book could have been condensed. Writer is an excellent researcher and good story teller.
