Something that always comes to my mind when I think of JP is a vast coniferous jungle, with ferns littering the forest floor. The ground is soggy, but not swampy and the forest is intercut with long, dusty plains and fern-covered rocks/canyons dripping with water. I also thing of ruined buildings and dinosaurs that have the right look to them i.e: a molted dark green T. rex with a large nasal and eye ridge, or an orange-brown raptor that has a rectangular-shaped head. Also, the images of rusty old equipment/structures, like a bridge, or a vine covered concrete structure always come to mind. Finally, I think of on-location jungle coupled with the most brilliant animatronic work and amazingly realistic sets all on top of a "life finds a way" theme. Oh and don't forget John Williams, his music is as recognizable as any theme out there.
