History The Long Canyon originated as the site of a stone quarry. In the 1970s, work performed by an excavator, caused an unexpected rupture of the water table. This resulted in the quarry flooding so quickly that the work crew was unable to retrieve their equipment, abandoning it to the water.
Description Now the site of a long lake, the Long Canyon is considered to be the largest submerged quarry in the Rostov region. The quarry is located south-west of the village Chistoozerny and south-east of Kamensk-Shakhtinsky. The lake is about wide at its broadest point, and deep. Its banks are high, rocky and steep. The lake is fed by underground streams, and its water remains cold regardless of air temperature.
