Author/Adventurist Ron Morehead, producer of the Sierra Sounds, has been known for decades for his world-wide research into the Bigfoot/Sasquatch phenomenon. To date, he comes closer than any other researcher to having a complete body of evidence. The Sierra Sounds are the only Bigfoot recordings that have been scientifically studied, time-tested, and accredited as genuine. Ron has documented his personal interactions with these giant beings and produced his story on a CD and also in a book, “Voices in the Wilderness.”

About The Science

Wednesday, June 11, 2014


Dr. R. Lynn Kirlin, a Professor of Electrical Engineering at the University of Wyoming, after a yearlong study of the recordings, presented his findings in a symposium at the University of British Columbia. It was his opinion that the formant frequencies found were clearly lower than for human data, and their distribution does not indicate that they were a product of human vocalizations and/or tape speed alteration.

Nancy Logan is a human sound expert in the State of California. In her opinion the vocalizations have a pitch range that is considerably more flexible than that of humans. They go much lower and much higher. “The rapid articulation is virtually impossible for a man to do. The vocalizations seem to have some elements of language, i.e. certain repeated phoneme patterns and a certain organization to the chattering… they are trying to communicate.”

Scott Nelson (2008), a Crypto-Linguist, with over 30 years’ experience concludes: “We have verified that these creatures use language, by the human definition of it. The analysis is finished. With the recognition and acceptance that these creatures do indeed speak and understand a complex language, a greater effort will be made to collect voice recordings and our analysis of the language will improve.”
