Subsequent events have made it clear that there are a lot of what one must call "ins-and-outs" to this story, and I therefore feel it best and only fair that I give Patterson's story first, and verbatim from my first interview. This went as follows [Footnote 36--Sanderson, Ivan T., "First Photos of 'Bigfoot', California's Legendary 'Abominable Snowman'", Argosy Magazine, February 1968; "More Evidence that Bigfoot Exists", Argosy Magazine, April 1968.]:
At three-thirty on the twentieth of October (1967) we were packing our horses back into one of the last remaining great wilderness areas, northeast of Eureka, California. Our saddlebags contained on one side rifles and grub and, on the other, ready-loaded movie- and still-cameras and other equipment. We were following a creek which had been washed out two years previously in the terrible floods that devastated most of northern California. This was some twenty miles up the access-road for logging, and about thirty-five miles in from the nearest and only blacktop road in this vast and as-yet-not-fully-mapped area of National Forest. [I have been up this Bluff Creek and, as a botanist I can tell you that it is rugged--four layers or tiers of trees, the tallest up to two-hundred feet, and a dense undergrowth. Also, the terrain goes up and down like a gigantic sawtooth. Author.]
We rounded a sharp bend in the sandy arroyo of the creek. Then it happened.
The horses reared suddenly in alarm and threw both of us. Luckily, I fell off to the right and grabbed my camera. Why? Because I had spotted what had turned our horses into mad broncos. About one hundred feet ahead, on the other side of the creek bed, there was a huge, hairy creature that walked like a man! 'Gosh darn it, Ivan', [he said] 'right there was a Bigfoot. And, fer pity's sakes, it was a female! Just wait till you see the film.'
