Sea Eye Lake, Karst lake in Shariboksad, Russia
Sea Eye Lake is a karst lake near Shariboksad, Russia, filled with bright green water and measuring roughly 45 by 50 meters across. The lake reaches a depth of about 39 meters and is surrounded by steep banks.
The lake appears in early Russian documents under its Mari name, showing the historical presence of indigenous populations in the region. These written records reveal a long connection between the lake and local communities.
The Mari people called this lake Müšyl, meaning crater, while Russian visitors later named it Sea Eye after observing the color of its water.
The lake is easiest to visit during warmer months when the surrounding paths are accessible. Be aware that water levels have dropped in recent years, which has changed how the lake appears.
The lake's distinctive leaf shape was created by karst processes that dissolved the surrounding rock and carved out an unusual depression. This geological formation makes it stand apart from other lakes in the area.
