The abandoned mines are located under the Gravity Falls Forest. There was an entrance under an abandoned church. The mines hold dinosaurs from the Jurassic and Cretaceous periods encased in tree sap.


Ancient plants preserved through time.

Sometime during the Jurassic and Cretaceous periods, a number of dinosaurs were somehow encased in a large amount of tree sap and preserved through the millennia.

In "The Time Traveler's Pig," an image of the abandoned mines appears on Blendin's camouflage suit.

In "Land Before Swine," the summer heat started melting the tree sap, and a pterodactyl was set free. Using an exit at the abandoned church above, it started wreaking havoc around town.

Local miners thought they were about to strike a mineral deposit but came across a massive network of underground caverns instead. While exploring the caverns, several miners went missing and died. Surviving miners reported hearing loud, high-pitched screeches, as though from a giant prehistoric creature somehow left over from the late Jurassic period. Jack Solomon, the owner of the mining company, partially blamed the canary who he believed should have dropped dead at any sign of trouble. The canary was later fired.[1]

Dinosaurs encased in tree sap.

When the pterodactyl kidnapped Waddles in front of the Mystery Shack, Dipper, Mabel, Grunkle Stan, and Soos set out to rescue him. They were later joined by Old Man McGucket, who was hiding away inside the abandoned church. Inside the caverns, the group noticed several remains of miners while exploring the area. Upon discovering the frozen dinosaurs, Stan considered making the place into a theme park. They also noticed other dinosaurs were becoming loose, and a baby pterodactyl was also born soon after they found Waddles, which ate by McGucket.

The mines received some superficial damage in the course of the group escaping from the pterodactyl, and the baby pterodactyl was later eaten from the inside out by McGucket. However, later in the episode, he appears to be alive and unharmed.

In season 2, in the episode, "Weirdmageddon 3: Take Back The Falls," several survivors of Weirdmageddon attempt to use the trapped dinosaurs to their advantage against their oppressors.
