That's where my friend saw it when he was a young boy. He was from LA, but was visiting friends with his family near the Oregon Dunes. He and all the other kids went for a walk to the beach for tidepooling. The beaches are wide there and the walk was through forest and dunes.
As they neared the beach there were vast piles of logs and trees piled up above the high tide mark from all the winter storms (anyone who has toured the wild West Coast has seen them).
A Sasquatch stood on the top of the log pile and screamed at them. They freaked and ran. He remembers it picking up huge logs and tossing them about.
They ran all the way back to the house and told the adults. The people who lived there said it was not dangerous. And, congratulated them for seeing a bigfoot.
