Mys Tunaycha (Tonnai Misaki) (46°52'N., 143°09'E.), lying 17 miles SSE of Mys Gimau, is a conspic uous red cliffy cape which rises from the surrounding low lands. It has a wooded summit that is more often clearly seen when the higher hills in the vicinity are obscured. The entire cape is fringed with reefs, parts of which dry, and shoals extend outward for about 0.8 mile from the shore especially in the NE direction. Ozero Tunaycha, one of the largest fresh water lakes on Sakhalin, is located within the shore S of Mys Tunaycha and is entered by a narrow channel, dry in parts, located immediately E of the cape. Although the water is generally brackish during the dry season, with the onset of heavy rains when there is a constant outward flow, the lake is nearly fresh. Ozero Izmenchivoye, a smaller lake, is located W of the cape and is connected to the sea by a narrow channel with a depth of 0.3m.
