Every summer, the water of this sacred saline lake in British Columbia evaporates to reveal dozens of vivid mineral pools — each one a different shade of green, blue, or yellow, depending on its precise chemical makeup. No two summers look the same.
From the road, it looks like something a child dreamed up: a mudflat covered in enormous polka dots, each one a different impossible color. Green, turquoise, yellow, white — arranged in clusters across a dry lakebed, glowing in the Okanagan sun.
Spotted Lake — or Kłlil'xᵂ in the Nsyilxcən language of the Syilx Okanagan Nation — is one of the most mineral-dense bodies of water on Earth. It holds massive deposits of magnesium sulfate, sodium sulphate, and calcium, plus trace amounts of silver and titanium. As summer heat evaporates the water, these minerals crystallize and separate into individual pools, each with a distinct color driven by its chemistry and the microorganisms living in it.
The Syilx people have revered this lake for centuries as a source of healing. During World War I, its minerals were harvested to manufacture ammunition — a jarring contrast to its sacred status. Today the lake is protected, and visitors can only view it from a roadside fence. The spots shift and change every season. You can never see the same lake twice.
