presence of more than 1 km3 of water in the caldera adds a risk of flooding, which may destroy Güroymak, a town of 15,000 people. Climate, flora and fauna of the caldera The climate of the caldera is unique for the Armenian Highland. It is the only place in the region where deciduous trees grow at high altitudes, owing to the high temperature and humidity and the protection from winds by the caldera walls. The caldera also hosts a few flowers and trees unique to the region. Velvet scoters (Melanitta deglandi) and two species of gull live and breed on the shores of Lake Nemrut. Since ancient times the bottom of the caldera is used for grazing by the nearby villages. Tourism Nemrut is considered one of the most spectacular volcanoes in the region. Its caldera can be accessed in the summer on 4x4 vehicles from the south or east side. Nemrut is covered with snow five months per year, and therefore the Turkish authorities are building a mountain ski resort and a 2,517 m long ski track on the slopes of Nemrut.
