The '''Lost River''' is generally gloomy and foggy, possessing a distinct greenish water tint that is mostly illuminated by the acidic brine pools as well as an eerie atmosphere with the occasional [[Ghostray]] cry. These pools cover almost all of the lower portions of the caverns. The green brine found throughout most of the cave system will harm the player, but the blue brine found within the '''Tree Cove''' is harmless.

It is mainly characterised by Crabsquids, and obscure rock structures otherwise known as 'Slime Pillars'. [[Gel Sack]]s and [[Aluminum Oxide Crystal]]s can be found scattered around the edge of the brine stream.

The '''Ghost Forest''' is a massive cavern served as one of the entrance areas of the '''Lost River''' (located in the [[Blood Kelp Zone|Northern Blood Kelp Zone]]).
A large chamber that leads from the main entrance of the '''Lost River''' (located in the second Blood Kelp Zone). This area is filled with whitish glowing flora on the sea floor and dark brown, [[Bioluminescence|bioluminescent]] giant Ghost Trees, and is also the starting point of the brine river. There is steep drop off at the back end of the '''Forest''', with a long brinefall, that leads to the '''Junction'''. From there, the player can either go straight forward into the '''Bone Fields''', or turn right to enter the '''Tree Cove'''.

The Lost River is a unique cave biome. It is a massive, frigid cavern system located deep under the surface.

Entrances to the Lost River can be found in both Blood Kelp Zones and in the Deep Grand Reef. The Cyclops is able to enter the Lost River through the Deep Grand Reef and Northern Blood Kelp Zone. The Cyclops can traverse the whole way into the Inactive Lava Zone.

Description

The Lost River is generally gloomy and foggy, possessing a distinct greenish water tint that is mostly illuminated by the acidic brine pools as well as an eerie atmosphere with the occasional Ghostray wails. These brine pools cover almost all of the lower portions of the caverns. The brine pools found throughout most of the cave system will harm the player upon direct contact, with the exception being the harmless blue brine found within the Tree Cove.

The Disease Research Facility is located in the Lost River, inside a cavern with its opening in the Junction.

The Lost River is composed of six distinct areas:  

<tabber> Bones Field=

"Bone Fields"

The Bones Field is a vast cavern within the Lost River, where a colossal skeleton of an unknown fauna can be seen laying, giving the Bone Fields it's name. It is connected to the Blood Kelp Trench via the Lost River Corridor, as well as the Ghost Canyon, each of them having their own flora and particular landscapes. The area also has its own cave system, the Bones Field Caves.

Corridor=

"Corridor"

The Lost River Corridor is the area connecting the Bones Field to the Blood Kelp Trench. It is mainly populated by Crabsquids, with obscure rock structures otherwise known as "Slime Pillars" growing on the sides. Gel Sacks and Aluminum Oxide Crystals can be found scattered around the edge of the acidic brine stream.

Ghost Canyon=

"Ghost Canyon"

The Ghost Canyon is a large passage featuring multiple caves and tunnels branching out from one huge "canyon". It is connected to the Bones Field from the south. Numerous roots and bioluminescent-tipped branches litter the sides and bottom of the brine-filled trenches.

A Precursor Cache that was set up to study a skeleton can be found here.

This area is also the entrance to the Lost River, from the Deep Grand Reef.

Ghost Forest=

"Ghost Forest"

The Ghost Forest is a massive cavern served as one of the entrance areas of the Lost River (located in the Northern Blood Kelp Zone).

The cavern is greatly populated by whitish glowing flora on the sea floor, as well as dark brown, bioluminescent giant Ghost Trees, and is also the starting point of the brine river. Brinefalls of various sizes are present within the area, and a smaller variation of the gargantuan skull located in the Bones Field can be found here.

Among the dense vegetation, dangerous predators such as River Prowlers and Blood Crawlers can be found lurking around here. This area is also one of the two locations in the Lost River where the juvenile Ghost Leviathan resides.

A Precursor Cache is present in this area, serving as a warp gate to the Primary Containment Facility.

There is also a steep drop off at the back end of the cavern, followed by a long brinefall, that leads to the Junction. From there, the player can either go straight forward into the Bones Field, or turn right to enter the Tree Cove.

However, the color of the brine is a bright blue, compared to the corrosive green of the other sections of the Lost River. Unlike the green brine, however, the blue brine also does not damage the player upon direct contact.

One end of the cavern opens to the northern passage leading to the Junction, and the other to a corridor leading to the Inactive Lava Zone. Roots and branches grow scattered on the brine lakes and numerous Ghostrays inhabit the chamber.

There is also a naturally formed bridge that connects the plateau to the northern side of the cavern, towards the Ghost Forest.

The Junction connects to the Bones Field to the south, the Ghost Forest to the north, the Disease Research Facility's cavern to the east, and the Tree Cove to the west.

Trivia

  • Like other segmented biomes (such as the Inactive Lava Zone), the Lost River's technical data divides it into the LostRiver_TreeCove, LostRiver_BonesField and LostRiver_BonesField again for the Ghost Canyon (this aids the AI in deciding music tracks, random events and creature behaviour).
  • The acid damage from the brine may be possible implementation/reference to the "Pillars of Silence" concept art, where enormous jets of acid dot an alien seabed.
  • The game also considers the actual brine to be a biome. It is labelled LostRiver_BonesField_Lake.
  • The Ghost Forest was originally known as the "Ghost Trees Chamber" before the Bones Update.[2]
