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.
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.
