The exact location of the original Stanley Pines Memorial Library becomes lost for a few centuries.

Buildings collapse, papers burn, servers crash.

One of the diggers finds an old Barbie doll missing an arm and with half it’s hair cut off, and Dipper holds it in his hands, and remembers when three small redheads decided to have a spa day with all of their dolls…
It disappears offsite and never makes it to the lab)
