Ruins of Ark Polaris

The Ruins of Ark Polaris is a Salmon Run stage in Splatoon 2. It features an egg basket atop a platform and ride rails leading back up from the lower areas.

Layout
Ruins of Ark Polaris features an elevated platform in the center with three ramps leading to the ground. The central platform has two ride rails that both encircle half of the top platform. Two of the ramps provide an additional level in-between the lower level and the top platform. The third ramp leads down to a sandbar behind the structure. During low tide, the water recedes to reveal a shoreline with a central area and outer sandbar ring separated by a crescent of water.

Notable Locations

 * Tower: The main feature of the stage is its immense verticality. The basket is located at the top most of the tower with three ramp paths leading up. There are also inkable walls to make climbing easier.
 * Lower Ride Rails: Five ride rails are located on the lower portions of the map. Three on the front side of the map and three on the back side, all these rails will act as quick and easy ways to take players back to the basket.
 * Upper Ride Rails: On the top of the map, there are two ride rails on opposing sides of the area, they both circle the top of the map and can be chained together.
 * Rear Beach: There is a small beach at the back of the tower.
 * Lowtide Sandbar: During low tide, this sandbar will be revealed. It is an open area with a horseshoe-shaped pool of water. The basket will be located at the center with ride rails leading in and outwards.

Tides
Also, the Grizzco boat is within one DU of the sandbar and coming up close with it allows you to hear the beginning music clip.
 * During high tide, the water will rise leaving only the top level and the pathways below it, rending the lower ride rails inaccessible. Salmonids will spawn from one of three paths.
 * During low tide, the water recedes to reveal a shoreline with a central area and outer sandbar ring separated by a crescent of water. The central area contains the basket and has ride rails leading to the outer ring. The outer ring also has ride rails leading to the center. There are paths of shallow water in the crescent that divides the inner and outer area that the Salmonid can cross at will.

Trivia

 * The internal codename for this stage in the game files is "Shakeride".
 * The sky on this stage is perpetually darker than other Salmon Run stages. While other Salmon Run stages take place during the early parts of the sunset during their normal waves, Ruins of Ark Polaris takes place at late dusk.
 * The background features the tail of a crashed space shuttle, presumably the eponymous Polaris.
 * The space shuttle has worn-out text reading "PRIVATE PROPERTY" in English, as well as featuring giant letters spelling "ICA".
 * Some walls in the stage feature signs reading "Active Bear Area" in English.
 * With the exception of s for Splatfests that promote real-world brands, this is one of the few in-game appearances of any written human language.
 * The stage name could also be a reference to the constellations Ursa Major and Ursa Minor, as the star named Polaris is part of Ursa Minor.
 * There is also the “Active Bear Area” signs that depict a larger bear (Ursa Major) on the sign above and a smaller bear on the sign below (Ursa Minor).
 * The bear warning signs also could be in reference to Mr. Grizz.
 * Bear tracks can be seen on the ground at low tide.
 * This stage marks the second appearance of ride rails in a multiplayer stage after Railway Chillin' and the first appearance in a regular stage.
 * Using will prevent the player from getting on the ride rail and using it while on the ride rail will result in the player immediately dropping off.
