+# Mountain Island+ +![MountainIslandHeaderImage](https://wiki.subnautica.com/sn/images/MountainIslandHeaderImage.png?345a6)+ +| Feature | Details |+| :--- | :--- |+| **Type** | Islands |+| **Depth Range** | 0 - 155 meters above sea level |+| **Temperature Range** | 20.5°C - 30.3°C |+| **Harvesting Nodes** | Shale Outcrop |+| **Points of Interest** | Quarantine Enforcement Platform, Alien Arch, Alien Arch Cache, Mountains Caves |+| **Cave Entrance Coordinates** | 335, 10, 1025 |+| **Music** | Violet Beau |+ +The **Mountain Island** is a large island biome located on top of a mountain range in the Mountains. It is situated 1000m northwest of the wreck of the Aurora and is adjacent to the Bulb Zone, Kelp Forest, Mushroom Forest, and the Underwater Islands. The island also harbors the Quarantine Enforcement Platform at its northern tip.+ +The island is shrouded by fog, making it invisible until one is relatively close. However, players can receive coordinates for its location from the Sunbeam.+ +## Description+ +The Mountain Island is characterized by rocks of various sizes and a fairly large mountain in the center, surrounded by an extensive shoreline. The island is connected to the Mountains Caves, with entrances accessible from both underwater and on land.+ +The Mountain Island can be fully explored on foot, featuring a small variety of flora such as Bulbo Trees, bioluminescent grass, and Pink Caps, as well as wildlife like Speckled Rattlers. Unlike the Floating Island, this island is part of a continental shelf.+ +### Exploration and Resources+ +The path to the summit is marked by Precursor technology; along the path, two Purple Alien Tablets can be found. Near the summit of the island is a Principal Alien Arch Cache connected to the Floating Island Arch.+ +Some of the caves lead to a lagoon, which houses many types of flora and connects to the island's base.+ +**Notable Wildlife:**+*   Cave Crawler+*   Skyray+ +**Notable Flora:**+*   Bulbo Tree+*   Pink Cap+ +**Resources:**+*   Diamond+*   Gold+*   Large Lead Deposit+*   Lithium+*   Salt Deposit+*   Purple Tablet Fragment+ +### Notes+ +*   The caves leading to the Alien Arch are extremely rich in rare resources whose acquisition normally requires exploring much more dangerous biomes. Shale Outcrops and Lithium in particular are abundant, providing easy access to Gold, Lithium, and Diamonds for anyone capable of handling a large number of Cave Crawlers in the area.+*   If the player opens their PDA in the direction of the Mountain Island from anywhere on the map (like using a spyglass), the clouds shrouding the island will glow a bright white. This shows the player which clouds are real or fake, revealing the exact location of the island. This method works regardless of which PDA menu is selected, but only during daytime and while above the surface. It also works on the clouds shrouding the Floating Island.+ +## Gallery+ +![Mountain Island Overview](https://wiki.subnautica.com/sn/images/thumb/MountainIslandOverviewDay.png/200px-MountainIslandOverviewDay.png?4eb0f)+*Mountain Island Overview*+ +![Ditto, at night](https://wiki.subnautica.com/sn/images/thumb/MountainIslandOverviewNight.png/200px-MountainIslandOverviewNight.png?204a3)+*Ditto, at night*+ +![Main part of the Mountain Island's beach](https://wiki.subnautica.com/sn/images/thumb/MountainIslandBeach.png/200px-MountainIslandBeach.png?43df8)+*Main part of the Mountain Island's beach*+ +![Birds-eye view of the Mountain Island's beach](https://wiki.subnautica.com/sn/images/thumb/MountainIslandBeachBirdsEye.png/200px-MountainIslandBeachBirdsEye.png?d1774)+*Birds-eye view of the Mountain Island's beach*+ +![Lagoon Entrance, found upon the beach](https://wiki.subnautica.com/sn/images/thumb/MountainIslandLagoonEntrance.png/200px-MountainIslandLagoonEntrance.png?62350)+*Lagoon Entrance, found upon the beach*+ +![Underwater Entrance, leading to the Lagoon](https://wiki.subnautica.com/sn/images/thumb/MountainIslandUnderwaterCaveEntrance.png/200px-MountainIslandUnderwaterCaveEntrance.png?bdce6)+*Underwater Entrance, leading to the Lagoon*+ +![A view inside the underwater caves](https://wiki.subnautica.com/sn/images/thumb/MountainIslandUnderwaterCaves.png/200px-MountainIslandUnderwaterCaves.png?c5720)+*A view inside the underwater caves*+ +![A small underwater cave at the base of the Mountain Island](https://wiki.subnautica.com/sn/images/thumb/MountainIslandSmallUnderwaterCave.png/200px-MountainIslandSmallUnderwaterCave.png?b0036)+*A small underwater cave at the base of the Mountain Island*+ +![Mountain Island Lagoon Overview](https://wiki.subnautica.com/sn/images/thumb/MountainIslandLagoonOverview.png/200px-MountainIslandLagoonOverview.png?fa71a)+*Mountain Island Lagoon Overview*+ +![Mountain Island Lagoon from a small cave above](https://wiki.subnautica.com/sn/images/thumb/MountainIslandLagoonTop.png/200px-MountainIslandLagoonTop.png?85403)+*Mountain Island Lagoon from a small cave above*+ +![Mountain Island Lagoon from underwater](https://wiki.subnautica.com/sn/images/thumb/MountainIslandLagoonUnder.png/200px-MountainIslandLagoonUnder.png?da9f5)+*Mountain Island Lagoon from underwater*+ +![A pathway leading up the side of the Mountain Island to the cave system](https://wiki.subnautica.com/sn/images/thumb/MountainIslandPathway1.png/200px-MountainIslandPathway1.png?da9f5)+*A pathway leading up the side of the Mountain Island to the cave system*+ +![A pathway leading from the Cave System to the top of the mountain](https://wiki.subnautica.com/sn/images/thumb/MountainIslandPathway2.png/200px-MountainIslandPathway2.png?39a26)+*A pathway leading from the Cave System to the top of the mountain*+ +![Ditto, opposite side](https://wiki.subnautica.com/sn/images/thumb/MountainIslandPathway3.png/200px-MountainIslandPathway3.png?238e0)+*Ditto, opposite side*+ +![The entrance to the cave system](https://wiki.subnautica.com/sn/images/thumb/MountainIslandCaveEntrance.png/200px-MountainIslandCaveEntrance.png?32ff1)+*The entrance to the cave system*+ +![A view inside the caves.](https://wiki.subnautica.com/sn/images/thumb/MountainIslandCaves.png/200px-MountainIslandCaves.png?2c865)+*A view inside the caves.*+ +![The caves of the island are full of Shale Outcrops and Lithium](https://wiki.subnautica.com/sn/images/thumb/MountainIslandResources.png/200px-MountainIslandResources.png?c5c0c)+*The caves of the island are full of Shale Outcrops and Lithium*+ +![A view of the Quarantine Enforcement Platform](https://wiki.subnautica.com/sn/images/thumb/MountainIslandQEP.png/200px-MountainIslandQEP.png?23567)+*A view of the Quarantine Enforcement Platform*+ +![The cave leading to the Arch](https://wiki.subnautica.com/sn/images/thumb/MountainIslandArchCave.png/200px-MountainIslandArchCave.png?fb52f)+*The cave leading to the Arch*+ +![The Alien Arch of the Mountain Island, unpowered](https://wiki.subnautica.com/sn/images/thumb/MountainIslandArchUnpowered.png/200px-MountainIslandArchUnpowered.png?dc1a7)+*The Alien Arch of the Mountain Island, unpowered*+ +![Ditto, powered](https://wiki.subnautica.com/sn/images/thumb/MountainIslandArchPowered.png/200px-MountainIslandArchPowered.png?143eb)+*Ditto, powered*+ +![Skyrays flying above the Mountain Island](https://wiki.subnautica.com/sn/images/thumb/MountainIslandSkyrays.png/200px-MountainIslandSkyrays.png?49317)+*Skyrays flying above the Mountain Island*+ +![Concept Art of the Mountain Island, along with the Quarantine Enforcement Platform](https://wiki.subnautica.com/sn/images/thumb/PrecursorArray.JPG/193px-PrecursorArray.JPG?2d226)+*Concept Art of the Mountain Island, along with the Quarantine Enforcement Platform*+ +## Bugs+ +*   On Xbox, the clouds shrouding the island aren't visible, making it quite hard to locate the island.
