I was looking through some of the early videos we have the other day and I wanna add on some interested finds and thoughts.
This area appear in the early video with this pond, where Anne turns around and a raptor jumps at you. Be aware that the video is really low quality to begin with.

The two things in the middle of the pond is two barrels floating around.
As Anne turns around, if you take a close look, you will see this Pylon:

This Pylon location also appear in one of the other Trespasser trailers, but with more engine-like settings:

Taking a look at the trees, this one appears to be using the early tree texture seen in the TestScene palm.
I wonder if this could be the location used for these images:

As a bonus, from one of the trailers:

This is the Jeep being pushed (probably by a force trigger) onto the Mayan Face.

I know this Biohazard barrel has been talked about before. I am very certain this is of the unused "oil" barrel, the one with the Oil logo on it - "Poilbarrel00-00". Why? The texture names:
"Sbiobarrel00t2.bmp"
"Sbiobarrel02t2.bmp"
"Sbiobarrel05t2.bmp"
It got the Bio in the name and several ones appear not to be used (01, 03, 04).
And another bonus, before the raptor jumps on you, you get a nice view of the area behind it:

A lot of foliage. I wonder if this was all part of one bigger early level to test things like water physics and foliage density. And that most early images actually comes from this level but in various areas?
