Journal #1 from Gravity Falls is a burgundy journal written by Ford Pines that documents the paranormal occurrences in the town of Gravity Falls, which first appeared in the episode "Gideon Rises." The cryptic contents of the ripped and torn book include drawings, symbols, text with missing words, and passages with unknown meanings.
The journal was written more than 30 years before the events of the cartoon Gravity Falls. It was the first of three journals written by Ford Pines about the strange activities he observed in the town. The author hid the second two throughout Gravity Falls in order to prevent anyone else from discovering the information inside them and using it to open the Universe Portal.
After hiding the other two journals, Ford trusted Journal #1 with his brother Stan, who threatened to burn it. This threat resulted in a fight between the two, which accidentally opened the Universe Portal. Ford was pulled into the portal and threw Journal #1 back to his brother before disappearing. Stan then began searching for Journals #2 and #3 in order to learn how to reopen the portal and find his brother. However, in the episode "Weirdmageddon Part 1," Bill destroyed all three of the journals.
