In the eastern part of the Izu Peninsula, many traces of old volcanic activities are found not only on the ground but also on the bottom of the sea. Several beautiful cascades like 'Joren-no-taki', 'Eboshiyama' hill, 'Dogashima' island and 'Jogasaki' irregular coastline were all formed by volcanic activities. Among these unique sceneries, Omuroyama hill and Ippekiko lake are the best examples. Omuroyama is a single-volcano, 580 meters high above sea level, which was formed by a single eruption about 4,000 years ago. The hill itself with an almost conical shape is 300 meters high, and the diameter of the bottom is 1,000 meters. An old crater, the diameter of 250 meters and 40 meters in depth, is found on the top of the hill, as shown in the first picture. The second picture shows Ippekiko lake commanded from the summit of Omuroyama hill. This round lake, which was formed by repeated eruption about 100,000 years ago, is a Marl Lake.
