Mount Nemrut & Crater Lake Mount Nemrut & Crater Lake, a stratovolcano located in eastern Anatolia, is one of many high mountains seen throughout this region. Nemrut is a dormant, active volcano. The last time it erupted was in 1441 and the crater on its top is where Nemrut Lake can be found. Nearby, the highest peak is Sivritepe (2935 m.), East Nemrut Hill (2625 m.), Tursuktepe (2828 m.) to the south and Nemrut Mountain Hill ( 2801m) to the west. Mount Nemrut’s broad basin is up to 6 km in diameter, holding the lake on the western edge. At 2400 meters altitude, it rests at a modest height above sea level; yet its surface spans 10 km2 and length 2700 m in east-west width. The waters of the salty lake are sweet. There are steep slopes with a height of 500 meters to 600 meters around the caldera with a base level of 2247 meters. In the eastern part of the caldera, there are Obsidian cones formed by eruptions after collapses, and Göl Hill reaches a height of 3485 meters with Ilıgöl located near the north end. The diameter of this circular shaped lake is approximately 500 meters wide and its deepest point has been determined to be 10 meters deep. Like Lake Nemrut it also has fresh water. Lava and tuff plateaus occupy large areas at footsides if these volcano's feetsides . Within the caldera, there are five lakes, numerous lava outlets, lava funnels, splash cones and six caves. The surface of Lake Nemrut, which is shaped like a crescent and has a surface area of approximately 15 km², is 2247 meters above sea level. This location is 600 meters higher than Lake Van. Volcanic material is made up of slag, pumice and obsidian. When the rocks in the region are examined, it is seen that they are composed of basalt, andesite and trachyte as well as fluid types which were formed by volcanic precipitation such as ash, tuff, pumice and ignimbrite. Mount Nemrut's hot spring is in the crater of Mount Nemrut. The temperature is 60 degrees and it has no facility. Visitors come with the belief that its water can cure rheumatism and skin diseases.
