Our long time member Tirademan (R.I.P. Scott McClean) compiled this extensive archive of Sasquatch related newspaper articles and donated it to the BFF before his passing. The earliest articles in this collection are from 1818 in Florida, 1877 (Australia), 1884 (Canada) and 1764 (Europe).
As a former ultrasound tech, I can say that ultrasound IS sometimes used for suspected appendicitis. Usually, the decision depends on the proper body type i.e. skinny. If the text comes back inconclusive, it is then often off to the CT. It's done this way to hopefully save the patient money if it can be located with ultrasound.
@Wolfjewel I am glad to hear you are ok and doing well. May you continue to heal.
And I would never leave @Madison5716 alone out there. If I could not treat whatever it is, I would like to think I could fashion a travois, and pull her and her pack out, albeit not as fast as I could when I was but a wee NorthBreeze.
I would add China/Tibet, India, Nepal, and Bhutan. I suspect the official discussions took place between the U.S., Russia, and China in the 1955-1970 timeframe and the realization that non-"discovery" benefitted all (including the creatures). From there the other nations were brought in on the quiet agreement and saw the wisdom in it right away.
I believe the United States government has known of these creatures for the better part of the 20th Century, and maybe even before 1900.
Very possible. But one thing is certain. Whatever they are, whether ape or human, the government's of the United States, Canada, and Russia know they exist.
Bigfoot are smart and elusive. But they are not so smart and elusive that they could have evaded detection for so long without a concerted government cover up of some sort or another.
