Gravity Falls Cemetery

The Gravity Falls cemetery is a cemetery in the town of Gravity Falls, Oregon, where the residents of the town bury their dead. Like most aspects of Gravity Falls, it houses its share of ancient historical secrets. The Underground cave is found below an angel statue here.

History
The cemetery is first mentioned when Mabel Pines says that she met Norman there. It was first visually seen when Mabel is going on her date with Norman; he accidentally falls in a grave before rising out of it, appearing to be like a zombie.

The cemetery is later seen when Dipper and Mabel are searching for the true founder of Gravity Falls in the episode "Irrational Treasure." They uncover a map from Journal 3 during Pioneer Day, and follow it to the Gravity Falls Library, and then to the Gravity Falls History Museum. Eventually, they discover that a piece of abstract art in the museum is actually a statue of an angel upside down, pointing. Mabel realizes that she has seen the statue in the cemetery, and she and Dipper go there straight away.

At the cemetery, they track down the statue. Mabel pretends to pick her nose with the angel's pointing finger, which surprisingly unlocks a secret passage, leading to the chamber guarding the secrets of Quentin Trembley, the embarrassing eighth-and-a-half president of the United States.
