English: Natural-colour image of Sivash. The shallow waters of Sivash appear in shades of peach, mustard, lime green, brilliant blue, muted blue-green, beige, and brown. Thick layers of silt coat the bottoms of the shallow marshes, which are rich enough in mineral salts to supply a local chemical plant. The marshes’ shallowness and chemical composition contribute to their unearthly colours in satellite imagery. Surrounding the marshy areas are agricultural fields, most of them rectangular, but some of them shaped by centre-pivot irrigation systems. Urbanized areas appear along the shores of the Black Sea, and highways curve and zigzag across the peninsula.
