The geography of Hakkari, which has been banned for a long time due to terrorism in the southeast of Turkey, has now started to welcome its visitors. Hakkari's magnificent Sat lakes and the Uludoruk (Reşko - Geliyaşin) summit (4,135m) of the Cilo mountains have become a national park. Turkey's largest glacier, Reşko (Uludoruk - Geliyaşin - İzbırak) Glacier is in Hakkari. The glacier in this photo is located at the foot of the summit. Its name is Erinç (Suppa Durek) Glacier.
