aries with season. In spring, when the snow from surrounding mountains melts, it can reach 90 m (300 ft), and in 1914 it reached 114 m (374 ft), overflowing the southern rim. The lake is a popular destination for hiking and sight-seeing. Maximum dimensions of the lake are around 800 m × 500 m (2,600 ft × 1,600 ft), but they significantly vary due to big changes in the water level. At the end of the summer the lake may completely disappear. In 1907, a road was built descending to the lake. In 1942, an earthquake caused a large rockfall, resulting in reduction of the lake's depth.
