Damage to plantlife on the seafloor suggests this may be the migration path of a huge, bottom-dwelling lifeform.
The Sea Treader's Path is characterized by a large mound of sand, rock, and gravel - which actually consists of a long, wide path paved with rocks and gravel going through a dark tunnel, with many types of flora decorating along the way, including Membrain Trees. It features a grand diversity of life forms, mostly originated from its bordering biomes, such as Spadefish. The stomping of the Sea Treader Leviathans can bring up Shale Outcrops.
There is also a rather large cave system connected to the aforementioned tunnel, with many entrances located from both inside and outside of the latter. A lot of Ruby and Lithium can be obtained there.
Sea Treader Leviathans roam this area, starting their migration from the Dunes to the Grand Reef, hence the name Sea Treader's Path. There is an entirely separate path that Sea Treader Leviathans roam on, starting from the Crater Edge next to the Crag Field and continuing through the Grand Reef, but this path does not connect to the path that goes to the Sea Treader's Path.
Wreck 7 can be found on the Sea Treader's Path.
One way to find the Sea Treader Leviathan is to swim southwest from Lifepod 5 using the Compass until you reach about -1467, 0, -707. Then, you should descend to about 290 meters and you should find a pack of Sea Treader Leviathans.
