Since 1992, Christopher O’Brien has investigated over one thousand paranormal events reported in the San Luis Valley–located in South-central Colorado/North Central New Mexico. Working with law enforcement officials, ex-military, ranchers and an extensive network of skywatchers, from 1992 to 2002 he documented one of the most intense waves of unexplained activity ever reported from a single geographic region of North America. His ten-year investigation resulted in the three books of his “mysterious valley” trilogy, The Mysterious Valley, Enter the Valley, and Secrets of the Mysterious Valley.

His meticulous field investigation of UFO reports, unexplained livestock deaths, Native American legends, cryptozoology, secret military activity and the folklore, found in the world’s largest alpine valley, has produced one of the largest databases of unusual occurrences gathered from a single geographic region.

He is currently working with a team of specialists installing a high-tech video surveillance and hard-data monitoring system in and around the San Luis Valley. His 2009 book Stalking the Tricksters distills his years of field investigation and research into an ingenious unified paranormal theory that is sure to create intense interest and controversy.

His latest book Stalking the Herd (600 pages) is being called “The Bible of cattle mutilations books” and has received dozens of positive reviews. It is the first book on the subject that objectively examines the unexplained livestock death phenomenon—one of the most perplexing mysteries of our times.

1 - Stalking the Trickster

Stalking the Tricksters: Shapeshifters, Skinwalkers, Dark Adepts and 2012

The subject of Trickster-ism has permeated human belief for millennia but today, in the 21st Century, very little is publicly known about “The Trickster.” Graced by many names including; fool, sage, coyote, Loki, men-in-black etc., tricksters have inhabited culture for millennia and this casual force has played pivotal roles throughout history. Author/field-investigator Christopher O’Brien redefines this hidden subject of “tricksters” from a new, fresh perspective and he begins a journey down to the enchanted southwest desert to study the many elusive tricksters of North American indigenous myth and lore. He quickly realizes, that for millennia, tricksters have been shrouded world-wide behind many guises such as skinwalkers, shapeshifters jokers, loki, jinn, sorcerers, witches and other dark adepts. And that they have burrowed deep inside human belief into the core of human culture. Cryptids, elementals, werewolves, vanishing hitchhikers, demons and dancing devils have been reported around the world for generations. But why? What are these forces? What is their agenda? O’Brien journeys out into the field to determine whether these phenomenal masks worn by the tricksters can provide us a direct conduit to the unknown today in the 21st Century. Could it be that these denizens of phenomenal events may be attempting to communicate a warning to humanity in this uncertain age of prophesized change? Reporting from places such as the Navaho, Apache and Hopi Reservations of Arizona, the four sacred mountains of the Four Corners, Mexico’s bizarre Zone of Silence and the Temple of the Inscriptions at Palenque in the Chiapan Highlands. O’Brien uncovers intriguing accounts that suggest there are beings walking among us able to utilize fantastic abilities. He realizes that subtle, deeply ingrained beliefs regarding these dark adepts with wild talents have subtly shaped cultural belief around the world for generations and today, these fantastic creatures continue to instill fear and awe. These adepts have been manipulating as he tackles, redefines and examines the mysterious world of the tricksters.

Stalking the Herd: Unraveling the Cattle Mutilation Mystery

Who or What is Behind the Cattle Mutilations?
The cattle mutilation phenomenon is an ongoing mystery that has endured for almost 50 years. What have we learned, if anything, from the countless reports filed? Who or what is behind the death and disfigurement of livestock reported as mutilated around the globe?
Are these deaths simply attributable to natural predators and scavengers? Or is the military/government somehow involved? Are the deaths the action of ritual “cultists” as police say the evidence would suggest? Is it possible that alien predators are involved, as some researchers and the media have suggested? Are mystery helicopters or UFOs related to the cattle mutilation phenomenon as many witnesses have claimed?
Regardless of who or what is responsible, what are the motivations behind perpetrating what may be the greatest unsolved serial crime spree of all time?
Stalking the Herd addresses these questions in depth and also offers an objective look at the history of our venerated relationship with cattle, among the first domesticated livestock. Is there a connection between these ritualistic cattle deaths and humankind’s ancient practice of animal sacrifice? Why are there no Brahman cattle mutilations in India where cattle are revered to this day? Are aliens gathering genetic material for unknown purposes? What about the thousands of pounds of scientific forensic evidence? Are some hidden sections of the military conducting secret projects that–for some reason known only to them–involve the mutilation of hundreds of livestock and other warm-blooded animals. Are they monitoring the spread of “mad cow” disease?
Stalking the Herd is an in-depth examination and analysis of this complex, multi-layered mystery and this book scrutinizes the various explanations that have been proposed over the years and proposes new theories that have chilling implications.

The Mysterious Valley

Like other residents of the strage communities of Crestone and the Baca, Christopher O’Brien was drawn to the sacred valley of Native American myth. He was soon compelled to document, in disturbing detail, the inexplicable events unfolding around him and the questions they raised:

What is the truth behind the nightly light show of UFOs pulsing and glowing across the sky?
What are the strange rumbling noises coming from underground?
What is the origin of a mysterious crystal skull found in the Baca?
And most frightening of all, who is responsible for the scores of cattle left bloodless and mutilated in inhuman fashion?

Including fascinating and sometimes frightening first-hand accounts by residents of the area, The Mysterious Valley reveals the story of one of the most bizarre regions on the face of the earth and its chilling implications for the rest of humanity.




Who were they?… Why did they come?… What did they leave behind?… Where did they go?… Will they return?…
