Gravity Falls, Oregon was founded in 1842 by 8½th president of the United States of America, Quentin Trembley. He "discovered" it by falling off a cliff on a horse that he was riding backwards. However, this fact was covered up by the U.S. government, and instead "local nobody" Nathaniel Northwest was officially recorded as the town founder. An X'ptho spaceship which crashed several million years ago is buried underneath the town, and the cause of the valley's creation. In addition, the valley is a soft spot in the fabric of reality, and so has several strange occurrences.
