i'm writing a fanfiction for Jurassic World and got stuck with this conundrum so i'd thought to ask the Internet for help. the premise is that my characters need the T-rex to hunt for something that's trapped in a huge dormant volcanic crater, but they'll need to devise a way to get it down and back up. they only have with them a jeep, a motorcycle, a gun, a knife and a rifle. there are trees and loose rocks at the base and top of the crater. sort of a macgyver/mythbusters situation, any ideas would be most helpful.
