Jurassic Park: Trespasser/Jungle Road

Jungle Road originally started as soon as the player moved out of the wooden fences in the Beach level. It would then continue a little ways past the Monorail station up until close to the Plantation House. This is where it was supposed to end and the Planation House level was to begin. However, eventually Plantation House was scrapped and merged with Jungle Road. The Beach level was also lengthened to take in some of the old Jungle Road assets, such as the monorail station which marks the end of the Beach level in the final.

Hidden Valley
The Hidden Valley is a Valley that was closed off in the final version of Jungle Road. Although it is closed off it still is possible to get into it via the TELE cheat, or if used in the ATX patch, the FLY and FLYTELE cheats as well. The area this valley is located in is near Cathy's Beach. If the player takes the path from the shore and follows it all the way back eventually they'll reach a dead end where the path does an impossible climb up a steep cliff near a lone Triceratops. It can be teleported to with the coordinates -2220,234,22. For a long time, it was speculated that the Valley was going to be used for a Triceratops stampede. However, it turns out that this area actually lead to a beach that was eventually replaced by "cathy's beach" from Plantation House. Unlike the final version, prototype build 96 has the valley completely accessible. Unlike the final, there is a lot of foliage. In the final, most of the foliage has been removed. The Lone Triceratops is also absent in the prototype.

Colt M1911A1
Located out of bounds floating in the sky at 22,79,2 in both the final and prototype build 96, Is a weapon not used anywhere in the final version of the game. This is the Colt M1911A1. In Build 96, the Colt is located in the same area and is in that prototype as well. However, there are indications it was used once in a much earlier build. An old pre-release screenshot depicts Anne aiming the gun at a Raptor. If shot down with a weapon (which can be difficult to do due to how high up it is though using the ATX patch's AIM cheat helps some.)and taken back into the level and used. When used in both Build 96 and the final, the Colt works but has no firing sound (unless the sound of static heard counts as a sound), has an absurd amount of ammo for a handgun and does an unusually large amount of damage. The flash material also uses a strange pallete. Anne also holds it sideways due to the magnets are placed different comparing to other guns when she picks it up.

Misplaced Voiceovers
Two voiceovers are misplaced and are just outside of the playing area to the right of Cathy's beach. (Coordinates -2614,368,11 and -2505,382,45 respectively.) One is a Hammond voice over describing how the shore looked over Trackless ocean all the way to Antarctica. The other is an Anne voice over talking about how she used to play in the woods when she was a kid, pretending she was on a spy mission. An early version of Jungle Road, using an earlier version of the Jungle Road terrain places the voiceovers exactly on the path from the beach through the hidden valley.
