In the Bigfoot Casebook (Updated) on page 56, they have a sighting report turned in by a 10 year old girl to Ivan Sanderson.
When: About 9 years ago, at about 10 O'clock in the morning.
Where: Near the Eel River above Eureka, California. At the edge of a meadow nar the river's edge.
Under what circumstances: My family and I were fishing on the Eel River. We had been camped in the vicinity for about two weeks and had had poor luck when it came to fishing. I used to go for a short walk before breakfast because there was a very pretty meadow about a mile or two from our camp and I used to love to see the mist rise off the grass. I was only about 10 years old at the time and the world of nature was something which both fascinated and enthralled me. I entered the meadow and proceeded to cross it in order to reach a small knoll on the other side. When I approached the foot of the knoll I heard a sound. It was the sound of someone walking and I thought perhaps my little brother had followed me and was going to jump out and try to scare me. I hollered "All right, stinker, I know you're there" Needless to say it was not my brother that appeared. Instead it was a creature that I will never forget as long as I live. He stepped out of the bushes and I froze like a statue. He or "it" was about 7 1/2 to 8 feet tall. He was convered with brown stuff that looked more like a soft down than fur. He had small eyes set close together and had a red look about them. His nose was very large and flat against his face. He had a large mouth with the strangest looking fangs that I have ever seen... His form was that of a human and he had hands and feet of enormous size, but very human looking. However, there was one thing that I have not mentioned, the strangest and most frightening thing of all. He had on clothes! Yes, that's right/ They were tattered and torn and barely covered him but they were still there. He made a horrible growling sound that I don't think could be imitated by any living thing. Believe me I turned and ran as fast as I could. I reached the camp winded and stayed scared all while we were there.
